How Does The Ignition System Work?
The word crank is derived from a part of the automobile engine called the crankshaft. The crankshaft is one of the most important parts of an automobile. Its main aim is to translate the rotation of the pistons in the engine into an actual movement of the wheels. Engine cranking is the term used when your car engine is not able to turn on.
The process of putting your keys in the ignition to the part where the car engine is working is not as complicated as it seems, but it does involve a few steps. These steps and the parts involved need to be checked if your car has some problems turning on. Once you know what’s wrong, then you will have a better idea of why it won’t crank.
As the name suggests, the ignition system is responsible for firing up a car. There are a few steps that are involved in this process. Most vehicles today use an electrical starting motor. This consists of 4 main parts.
No Crank No Start, Ignition System Components #1: Battery
The battery is the most basic but important part of the ignition system. It is the vehicle’s battery that provides the electrical current to power up an automobile. The battery also supplies additional electricity when a vehicle is kept on ignition.
The battery is also responsible for the working of all the electronics in a vehicle. Hence, any issue with the battery can cause the whole car to have multiple problems.
No Crank No Start, Ignition System Components #2: Ignition Switch
The ignition switch is the component responsible for the flow of electricity during the time of ignition. The standard ignition switch has 4 positions.
- Off position/lock – This is the position when no part of the vehicle is receiving any electrical supply. You can take the key out and lock the steering with a little movement. At this position, no electrical part of your car will be working.
- Accessory – This position allows the car stereo along with some other basic electronics to be switched on. You cannot take out the key when in this position.
- Ignition/on – The ignition position allows all the electronics in the car to work properly. The key cannot be removed at this point and this position is the default position that the key returns to after you crank the engine.
- Start – The key needs to be turned to this position to crank the engine. You need to let go of the key after the cranking of the engine key as it returns to the ignition position. Holding the key in the start position can damage a vehicle’s spark plug.
No Crank No Start, Ignition System Components #3: Starter Relay
The starter relay is responsible for converting the small electrical current sent by the ignition switch to a larger current which is needed for the cranking of the engine. The starter relay is an important part of the ignition system, as the vehicles without this part would need switches and wires double their size to hold a current that large.
No Crank No Start, Ignition System Components #4: Battery Cables
Battery cables are multistranded wires which are rather large in size. They are responsible for carrying such a large electric current into the starter motor.
No Crank No Start, Ignition System Components #5: Starter Motor
The starter motor is the final part of the ignition system. It is responsible for the cranking of the engine during ignition and allowing the whole process to take place. When the ignition switch is turned on, the starter motor is engaged. It allows the crankshaft to turn. Then, it’s followed by air being sucked into the cylinders.
The starter motor has two gears on it. When the electrical current reaches these gears, they mesh together while the motor spins the engine. While all of this takes place, fuel and spark are introduced to the cylinders, igniting them, which in turn starts the engine.
As the vehicle starts working and the engine begins to spin faster than the starter, a gadget called the Bendix Drive separates the starter and the engine. This is when the starter disengages, and the vehicle’s ignition system’s work is done.
What To Do When Your Car Won’t Start (No Crank No Start)
Every problem has a list of solutions that helps rectify and get rid of that problem. The first part of tackling the “no crank, no start” problem is to diagnose and make sure which part of the ignition system is causing the problem.
Once the problem has been diagnosed, you can take your vehicle to a mechanic near you or try solving the problem on your own. Here is a list of problems and troubleshoots that can help you get over this problem.
No Crank No Start, Diagnosis #1: Dead Battery
One of the most basic causes for the “no crank, no start” problem is simply a battery. The battery is one of the most important components of a car. It is responsible for turning on all the electronic components of a car. Alongside that, the battery is also responsible for providing the spark to ignite the engine into starting.
A battery being low on charge or if it’s completely dead is a big reason why your vehicle won’t turn on. There are several reasons why your car battery is dead or low. It can simply be dead because an electrical part is left turned on for a long period of time.
For example, the headlight, parking light, or an electrical outlet plugged into your vehicle. Your battery can also drain if your car is parked for a long period of time or simply because you have an old battery. The old battery usually tends to drain out within a day of no usage.
If this is the case of why your car is having this issue, the car won’t have enough power to turn the engine. This can be easily diagnosed, as your car would make a clicking noise when you try to turn it on, or the starter may turn very slow when you attempt to turn your engine on.
How To Check Your Battery
To check if your battery is working or not, you can follow some simple methods
- You can keep your ignition switch on the accessory or ignition stage and see whether your vehicle electronics are not functioning properly, or if the light present on the dashboard is dimmer than usual.
- The second method by which you can check your battery is by checking the voltage through a multimeter tester. The multimeter tester indicates and shows the voltage the battery is emitting. The voltage of a normally functioning battery should be around 12.6 volts. If your car battery shows less than 12 volts it means that the battery is discharged.
- The third way you can check your battery is with a carbon pile or an inductance tester. A carbon pile is a device that hooks onto the battery of a vehicle and is used to determine the voltage a battery is emitting. This gives the most accurate voltage reading emitted by the battery. If the voltage shown on the scale is less than 9 volts, it is an indication of a bad battery that needs replacing. On the other hand, when talking about the inductance tester method, is considered to be easier than the carbon pile testing method. This device needs to be hooked onto the battery and displays information that is on the battery label. This device lets you know whether the “no crank, no start” condition was caused due to the battery.
There are several solutions to this battery problem-
- Jumpstart – Jump starting a car is the process where you connect your car battery to another car’s battery through a set of jumper cables (once you’ve figured out how to put on jumper cables). This allows the battery from your car to supply enough current to turn the vehicle’s engine. After jump-starting your vehicle, you need to leave it on for a while as it will help the battery to recharge (only if your battery is in good condition). If your battery is old, this process might not help you a lot.
- Recharging – Several workshops have battery recharge stations. Simply unhook your battery brace and disconnect the wires. This requires that you take the battery out. You can then give it to the workshop for recharging, and hook it back up once it’s fully recharged.
- Replacing – If your battery is not in the best condition, and is more than 5 years old, your car needs a new battery. The battery may not seem like a very important part of your car, but it’s responsible for making the whole car run. Also, a faulty battery can cause some problems down the road.
Symptoms of a Dead Battery
Understanding the signs of a dead battery is crucial to prevent finding yourself stuck with a ‘no crank, no start’ issue. Here are some key symptoms:
- Dim lights and Electrical Issues: One of the first signs of a dying battery could be dimmer headlights or other electrical issues, such as power windows moving slower than usual.
- Slow Engine Crank: A weak or dead battery might not provide enough power to crank the engine, resulting in a slow crank or no crank at all when you try to start the vehicle.
- Clicking Sound: If you hear a rapid clicking noise when you try to start your car, it’s often a sign of a dead battery. The clicking comes from the starter motor not receiving enough power.
- Dashboard Warning Light: If the battery warning light on your dashboard or a check engine light illuminates, it could be hinting at a problem with your battery.
- Swollen Battery Case: A battery case may swell due to the heat generated when the battery charges and discharges. This usually indicates that the battery is at the end of its life.
- Old Age: A battery’s performance decreases over time. If your battery is between 3-5 years old, it’s a good idea to get it checked.
How to Jump Start a Dead Battery
Knowing how to jump-start a car is a valuable skill. Here’s a simple guide:
- Preparation: Start by turning off both cars. Position the functioning car close enough so the jumper cables can reach both batteries, but make sure the cars do not touch.
- Connect the Cables: Attach one end of the red (positive) jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the good battery. Connect one end of the black (negative) jumper cable to the negative terminal of the good battery and attach the other end to a metal part of the engine block on the car with the dead battery. Avoid connecting directly to the negative terminal.
- Start the Good Vehicle: Start the working vehicle and let it idle for a few minutes to charge the dead battery.
- Start the Dead Vehicle: Attempt to start the vehicle with the dead battery. If it starts, let both vehicles idle for at least five more minutes to ensure a good charge.
- Remove the Cables: Remove the cables in the reverse order you attached them. Be cautious not to let the cables touch each other or the cars.
- Drive the Revived Vehicle: Drive the vehicle that was jump-started for at least 20-30 minutes to allow the battery to charge fully. If it doesn’t start again after turning it off, it’s likely time to replace the battery.
Car Battery Replacement Cost
The cost of replacing a car battery depends largely on your vehicle’s make and model, as well as the type of battery you need. Here’s a basic guide:
- Battery Cost: A new car battery typically costs between $50 and $200, but the price can vary depending on size, brand, and type. Batteries for larger vehicles or specialty batteries for electric or hybrid cars tend to cost more.
- Labor Cost: If you choose to have the battery professionally installed, factor in labor costs, which can range from $10 to $100.
No Crank No Start, Diagnosis #2: Security Or Key-Shaped Light Flashing
The technology used in vehicles these days is very advanced. Some of these modern cars come with something called an immobilizer or a security system that only allows the car to run with the correct key.
The ignition key has a chip inside with a security code. When the key is inserted, the security system does a quick scan of the chip and only allows the car to start once the code has been scanned and verified. Usually, the “security” light comes on for a couple of seconds, checks the security code, and then turns the car on.
If the vehicle’s security light remains on or starts blinking, it means that there is an issue with the security system of your vehicle. It means that the security system did not recognize the key which was inserted and it won’t allow the car to turn on. You can find more information about this in the owner’s manual.
This issue can also be tracked by reprogramming the vehicle security code, which can easily be done at any service center or automobile workshop.
Signs of Security System Issues
Security system glitches can often manifest themselves in some particular ways. Look out for these signs:
- Security Light Stays On: The security or key-shaped light on your dashboard should go off shortly after you insert the key. If it stays on, it could indicate a problem with the immobilizer.
- Engine Doesn’t Start: If you’re facing a ‘no crank, no start’ issue and the security light remains on, your car’s security system might be preventing the engine from starting.
- Intermittent Issues: Sometimes, the car might start perfectly at times but refuses to crank at others. This sporadic behavior can also hint at a problematic security system.
Triggers for Security System Problems
Security system issues usually crop up due to these reasons:
- Faulty Key: If the chip inside the key gets damaged or the key gets worn out, the security system may not recognize it.
- Damaged Transponder: A faulty transponder in the ignition switch might fail to read the key’s chip correctly.
- Electrical Issues: Any electrical glitches in the system, including wiring problems or a weak battery, could also cause the security system to malfunction.
Diagnosing a Faulty Security System
If you suspect a security system issue, you can perform these basic checks:
- Check the Key: Make sure the key isn’t damaged or overly worn. Try using a spare key if you have one.
- Observe the Security Light: Pay attention to the behavior of the security light. If it blinks rapidly or remains on, it can point to an issue.
- Scan for Error Codes: Using an OBD-II scanner, look for any error codes related to the security system.
DIY Fixes for Security System Problems
In some cases, you might be able to address security system issues yourself:
- Reset the System: Try resetting the security system by turning the ignition on and off a few times.
- Use a Spare Key: If you have a spare key, try using it. It could be that the issue lies with your regular key.
- Battery Disconnect: Disconnecting and reconnecting the battery can sometimes reset the security system and resolve the problem.
Security System Repair Costs
The cost of fixing a malfunctioning security system depends largely on the issue. Here’s a rough guide:
- Key Replacement: Getting a new key made can cost anywhere from $50 to $200.
- Transponder Repair: Fixing a faulty transponder can range between $100 and $400, including labor costs.
- System Reprogramming: Reprogramming the system at a service center could cost around $50 to $200.
In all cases, it’s best to get a quote from your service center as prices can vary based on your location and the make and model of your car.
No Crank No Start, Diagnosis #3: Battery Wiring
The wiring of the battery may also be at fault causing your car not to turn on. If the wiring is loose or broken, it may disrupt the flow of electricity to the ignition system. Due to this, there may be a loss in electrical load causing the vehicle to behave as if the battery is discharged or not connected.
Symptoms of Faulty Battery Wiring
Certain telltale signs can hint at a problem with your battery wiring. Look for these symptoms:
- Dim or Flickering Lights: If the headlights or dashboard lights dim when you start the car or flicker while driving, it could suggest a wiring issue.
- Slow Cranking: If your car cranks more slowly than usual but the battery is in good condition, the problem might lie in the wiring.
- Clicking Sound: A clicking sound when trying to start the car can also indicate a problem with the wiring.
Common Causes of Wiring Problems
Battery wiring issues can stem from several causes:
- Corrosion: Over time, the battery terminals can become corroded, which can disrupt the electrical connection.
- Loose Connections: Loose or broken wires can prevent the flow of electricity from the battery to the rest of the car.
- Wear and Tear: The wires connecting your battery to your car can wear out over time, especially in harsh conditions.
Diagnosing Battery Wiring Issues
You can follow these steps to diagnose battery wiring issues:
- Visual Inspection: Check the battery terminals for any visible signs of corrosion, damage, or loose connections.

- Cleaning: If the issue is corrosion and you decide to clean the terminals yourself, the cost is essentially free, save for the price of the cleaning solution.
- Tightening: Similarly, tightening loose connections yourself won’t cost you anything.
- Replacement: If the wiring needs to be replaced, the cost can range from $50 to $200, including parts and labor, depending on the complexity of the wiring and labor rates in your area. Always obtain a quote from your mechanic for an accurate cost estimate.
No Crank No Start, Diagnosis #4: Crankshaft Positioning Sensor
A broken or faulty crankshaft positioning sensor is one of the most common causes of the, “no crank, no start” problem. If this sensor is not working properly, it may cause the vehicle’s inner computer, the ECU, to not function properly.
Signs of a damaged crankshaft positioning sensor are:
1. The Tachometer On Your Car Won’t Function Properly
A sign of a damaged crankshaft positioning sensor is a faulty tachometer. The car’s ECU needs to relay the engine speed back to the tachometer. If the tachometer fails to do that or shows a fault, that means your car has a damaged sensor.
2. Decrease In Fuel Efficiency
Another sign of a fault in the crankshaft positioning sensor is the depreciation of your vehicle’s fuel economy. Your gas mileage will be lower than usual and if left unchecked, can cause the “no crank, no start” problem.
3. Ignition Sparks
Due to the faulty sensor, the ECU will not be able to turn the car on in an optimum way. The computer won’t be able to give the engine any spark, causing the engine to crank but not start.
4. Rough Driving
Because the computer will be receiving wrong information from the sensor, it will cause a very uncomfortable and rough driving experience. It can cause the car to misfire, or even stall completely. Engine stalling is a very unsafe driving situation for you and the people around you.
Reasons for a Faulty Crankshaft Position Sensor
The crankshaft position sensor is a vital component that feeds the Engine Control Unit (ECU) with information about the speed and position of the crankshaft. The causes of failure could be:
- Heat and Vibration: Excessive engine heat and vibration can cause the sensor to fail over time.
- Aging: Like any other component, the crankshaft position sensor is subject to wear and tear, and can degrade over time.
- Damage: Physical damage due to accidents or road debris can affect the sensor.
Troubleshooting the Crankshaft Position Sensor
To determine whether the crankshaft position sensor is faulty, you can perform the following steps:
- Check Engine Light: An illuminated check engine light can point toward an issue with the sensor. Use an OBD-II scanner to read the specific error codes.
- Visually Inspect: Look for physical damage or loose connections.
- Resistance Test: Using a multimeter, you can test the sensor’s resistance. Check your vehicle’s manual for the proper resistance range.
Fixing a Faulty Crankshaft Position Sensor
You can try the following steps to fix a faulty crankshaft position sensor:
- Clean the Sensor: Sometimes, oil or grime can cause issues. Cleaning the sensor might solve the problem.
- Check Wiring: Ensure the wiring of the sensor is in good condition and properly connected.
- Replace the Sensor: If cleaning doesn’t work and the wiring is intact, the sensor might need to be replaced. Make sure the vehicle is off and cooled down before starting this task.
Crankshaft Position Sensor Replacement Cost
The cost to replace a crankshaft position sensor can vary greatly depending on the make and model of your vehicle. The sensor itself can range from $20 to $100, and labor costs can run from $70 to $130. Always check with your local mechanic or service center for an accurate quote.
No Crank No Start, Diagnosis #5: Starter Won’t Crank
This is a very common issue in older cars with many miles on them. This issue can be caused due to several reasons-
- The ignition switch could have gone bad because of the wear and tear of the automobile.
- The starter motor itself or a starter solenoid could be bad.
- There could be a problem with the vehicle’s security system or the ECM (Electronic Control Module) which may prevent the starter from operating.
- The starter solenoid control wire could have broken down.
These are just some of the technical problems your vehicle might be facing. If you think your vehicle is facing any of these problems, you should show it to a mechanic or a technician as soon as possible, before there is any further damage to your car.
Recognizing a Faulty Starter
Certain signs can indicate that your starter isn’t cranking:
- Loud Clicking or Grinding Noise: A clear sign of a faulty starter is a loud clicking or grinding noise when trying to start the vehicle. This could be due to worn-out gear on the starter or flywheel.
- Lights but No Start: If you see the dashboard lights turning on, but the car doesn’t start, it could be a faulty starter.
- Starter Stays On After Engine Started: If the starter keeps running even after the engine has started, this could be a sign of a faulty ignition switch or a sticky solenoid.
Tracing the Root Cause
Several reasons could cause a starter not to crank:
- Worn-Out Ignition Switch: Over time, the ignition switch might wear out due to constant usage.
- Starter Motor or Solenoid Failure: Internal parts of the starter motor or solenoid could go bad due to age or other conditions.

Car Cranks But Won’t Start
If your vehicle’s engine is cranking, that means that electrically everything is all right with your car. But if your car still won’t start, here is a list of things you need to check to get rid of the problem you are facing.
Car Cranks But No Start, Diagnosis #1: Damaged Fuel Systems
The fuel pump is responsible for supplying the right amount of fuel to the engine at all given times. The “no start” issue may be caused by a fault in the fuel pump, fuel injector, or fuel line. Unfortunately, there is no way around a broken fuel pump and you will have to get a new one installed or find a replacement for the broken one.
1.1 Symptoms of a Damaged Fuel System
When the fuel system is damaged, there are certain symptoms that might hint at the problem. You may notice that your car takes longer than usual to start, or it may not start at all. The engine might sputter at high speeds or lose power during acceleration.
Decreased fuel efficiency and stalling when the engine is under stress, like during uphill drives, are also common symptoms. An engine misfire or the presence of a strong gasoline smell can also be indicative of a damaged fuel system.
1.2 Causes of Fuel System Damage
Several factors can cause fuel system damage. A fuel pump can fail due to age, poor maintenance, or even a bad fuel mixture. The pump can also overheat if you regularly drive with a low fuel tank, as the gasoline acts as a coolant for the pump.
Fuel injectors can become clogged with deposits if low-quality fuel is frequently used, leading to their malfunction. Similarly, fuel lines can deteriorate or get clogged over time, impeding the flow of fuel to the engine.
1.3 Diagnosing and Troubleshooting a Damaged Fuel System
To diagnose a faulty fuel system, begin by checking the fuel pump. When you turn the key to the ‘on’ position, you should hear a humming sound for a few seconds, which is the fuel pump building pressure. If you don’t hear this, the pump might be at fault. To troubleshoot further, use a fuel pressure gauge to check if the pump is delivering the correct amount of fuel to the engine.
For fuel injectors, if your engine is misfiring, idling rough, or not starting, a fuel injector test can be done using a mechanic’s stethoscope. Listen for a clicking sound which indicates that the fuel injectors are working properly.
Finally, inspect the fuel lines for signs of wear, damage, or leaks. If the fuel lines are blocked, you might also notice decreased fuel efficiency or power loss during acceleration.
1.4 Repairing a Damaged Fuel System
Repairing a damaged fuel system often involves replacing faulty components. A fuel pump can be replaced by draining and removing the fuel tank, then replacing the pump. However, this is a complex task that requires special tools and safety measures due to the flammable nature of gasoline.
A clogged fuel injector can sometimes be fixed by using a fuel injector cleaner added to the fuel tank. However, if the clog is severe or the injector is damaged, it will need to be replaced.
Fuel lines can often be repaired by replacing the damaged section of the line, although in some cases, the entire line may need replacement. Again, this is a task best left to professionals due to the risks of working with gasoline.
1.5 Repair and Replacement Costs for a Damaged Fuel System
The cost to repair or replace parts of a damaged fuel system can vary. On average, replacing a fuel pump can cost between $600 and $1000, including labor. Replacing a fuel injector is slightly less expensive, typically ranging from $500 to $800.
Replacing fuel lines is usually cheaper, at around $100 to $300, but can be more if the entire line needs to be replaced. Please remember these costs can vary greatly depending on the make and model of your vehicle and the rates of your local mechanic.
Car Cranks But No Start, Diagnosis #2: Fault In The Fuel Gauge
It is also possible that a faulty or broken fuel gauge might be giving the wrong reading to your vehicle. Your vehicle may be simply out of gas, which is causing the vehicle engine not to turn on.
2.1 Symptoms of a Faulty Fuel Gauge
The most obvious symptom of a faulty fuel gauge is an incorrect fuel level display. Your gauge may show that you have a half tank of gas when in reality, you’re running on fumes. You might find the gauge fluctuating wildly, stuck on full or empty, or not moving at all.
Other signs can include your vehicle running out of fuel unexpectedly, or your “Check Engine” light might turn on if your vehicle’s computer system detects a problem with the fuel level sensor.
2.2 Causes of Fuel Gauge Faults
Faults in the fuel gauge usually result from one of two components – the gauge itself on the dashboard or the fuel level sensor in the tank. The gauge can break due to electrical faults or simply wear and tear over time.
On the other hand, the fuel level sensor, which is a float connected to a potentiometer, can get stuck or wear out, giving inaccurate readings. Corrosion due to water or debris in the fuel tank can also affect the sensor’s operation.
2.3 Diagnosing and Troubleshooting a Faulty Fuel Gauge
To diagnose a faulty fuel gauge, you can start by checking for a blown fuse. If the fuse is intact, you can perform a gauge self-test (if your vehicle has this feature) to check if the gauge itself is functioning correctly.
If the gauge appears to be working, the issue might be with the fuel level sensor in the tank. Testing this requires a multimeter and a basic understanding of vehicle electronics, as you’ll need to test the sensor’s resistance at various fuel levels. If the resistance doesn’t change as expected when the fuel level is altered, the sensor might be faulty.
2.4 Repairing a Faulty Fuel Gauge
Repairing a faulty fuel gauge typically involves replacing the broken component – either the gauge itself or the fuel level sensor. Replacing the gauge involves removing the dashboard, which can be a complex task depending on the vehicle model.
Replacing the fuel level sensor usually requires removing the fuel tank to access the sensor. In some modern cars, the fuel level sensor is integrated with the fuel pump module, meaning you would need to replace the entire unit.
2.5 Repair and Replacement Costs for a Faulty Fuel Gauge
The cost of fixing a faulty fuel gauge can vary. Replacing the gauge on the dashboard can cost between $200 and $500, depending on the complexity of the dashboard design. Replacing a fuel level sensor can range from $250 to $800.
If the fuel level sensor is part of the fuel pump module, replacing the entire unit can cost upwards of $1000. As always, these costs can fluctuate based on your vehicle’s make and model and your local mechanic’s rates.
Car Cranks But No Start, Diagnosis #3: Damaged Alternator
3.1 Symptoms of a Damaged Alternator
There are several symptoms that may indicate a damaged alternator. The most common is the illumination of the battery or charging system warning light on the dashboard. Other symptoms include dimmed headlights and interior lights, a weak battery, frequent need for jump starts, or the vehicle may lose power and stall while running.
In extreme cases, a whining or grinding noise may come from the engine compartment, which is usually a sign of alternator bearing failure.
3.2 Causes of Alternator Damage
The alternator can become damaged due to several reasons. Over time, the alternator’s internal components can wear out, leading to failure. An overheated alternator, caused by a faulty cooling system or belt, can also lead to its failure.
Poor electrical connections, a worn-out belt, or an overly tight belt can harm the alternator. Exposure to extreme weather conditions or contaminants can also damage the alternator.
3.3 Diagnosing and Troubleshooting a Damaged Alternator
To diagnose a faulty alternator, start by visually inspecting it for obvious signs of damage like a broken belt or poor electrical connections. You can use a multimeter to check the voltage output, which should typically be around 14 volts with the engine running. If it’s significantly lower, your alternator may be the issue.

No Crank No Start, Car Battery, and Starting Issues: Need-to-Know Facts
- Low battery water levels can cause internal shorts that may ignite the gases inside the battery and cause it to explode.
- Always check the battery water before doing any work on the battery.
- If in doubt, cover the battery with a heavy blanket when trying to jump-start a dead car.
- A spark under water cannot ignite anything. If the battery fluid level is above the internal battery plates, the spark will not cause an explosion.
- When a car won’t crank over and start, turn on the headlights and see what color they are.
- White and bright headlights indicate that the battery has 12 volts, but it does not tell if the battery can provide the amps necessary to turn the starter over.
- Headlights dimming or going out can indicate a bad connection, and wiggling, pushing, and pulling the battery cables can help restore brightness.
- If the starter is bad, hitting it with a hammer a few times can make it work, and the engine will start.
- The correct jump start procedure is to hook up both positive cables first, then the dead car’s negative cable, and the good car’s ground cable to a good ground.
- Watching the headlights while trying to start the car can provide clues about what is wrong, such as whether power is getting to the starter solenoid or if the battery is incapable of handling a huge request for power.

FAQs On No Crank No Start
If you’re still curious to learn more about the ‘no crank no start’ issue, our FAQs here might help…
Why Won’t My Car Start
There are countless reasons to explain why your car isn’t starting. The most common cause is electrical-related. For example, you might be dealing with a weak or dead battery. Or, there’s an issue with the electrical supply and charging as a whole, such as a faulty alternator, damaged cables, blown fuses, malfunctioning starter, or a bad ground wire. Beyond electrical concerns, there may be mechanical issues that are preventing your car from starting. For instance, you may be dealing with a bad fuel pump, a clogged fuel filter, or a leaking fuel line. Otherwise, there could be faults within the ignition system or even problems with your car keys and the anti-theft system.
How To Start A Car With A Bad Starter
Oftentimes, your car’s failure to start isn’t because of a bad starter, but due to a weak charge from the battery. In this instance, you might try giving your car a jump-start and letting the battery charge. Once it has a sufficient charge (usually by boosting it via a jump-start and letting the engine run for 5 to 20 minutes), you can try starting up the car. If it’s still not starting, you can then consider bypassing the starter relay altogether. You can do this by placing the shaft of the screwdriver on the starter solenoid’s S terminal and letting the tip touch the solenoid’s battery terminal. Then, turn on the ignition, and remove the screwdriver.
Where To Hit Starter With Hammer
If you’re still unable to get your car to start, it’s quite likely that you’re dealing with a bad starter motor. Although you can permanently fix this issue by replacing or repairing the starter motor, you could use a hammer as a possible quick fix to at least get your car going. This is because the starter motor, over time, can develop certain dead spots between its armature and field coils. To close that gap and remove the dead spots, you can gently tap on the back of the starter motor with a hammer. Do so gently, and keep tapping 4 to 5 times (in quick succession, but lightly), usually by the rear, side, or top of the starter motor.
What Sensors Can Cause A Car Not To Start
Given how intelligent cars have become these days, electronic faults such as bad sensors can quite easily cause your car to not start. Some of those sensors include a camshaft and crankshaft position sensor, respectively. Without knowing the state or positioning of either the camshaft or crankshaft, your ECU may prevent the engine from starting. On top of that, there’s the fuel pressure sensor. Without it, the fuel system might not be able to activate and send fuel to the engine. Moreover, a faulty MAP (manifold absolute pressure) sensor, MAF (mass airflow) sensor, oil pressure sensor, or throttle position sensor, among others, would likewise prevent your car from starting.
How To Start A Car With A Bad Fuel Pump
Without a properly working fuel pump, your engine won’t be able to receive a sufficient (if any) amount of fuel to ignite it. Thus, causing it to not start. However, there are ways to start a car without a functioning onboard fuel pump. For example, you can try attaching a fuel pressure gauge, or a manual pump. This way, you can try to apply manual pressure to get some fuel flowing into the engine to at least get it started. You could do this using something like a mattress pump. Other than that, it’s also a good idea to keep your engine warm and heated, as once the car becomes cool again, the fuel pump would reset itself once more.
How to Test Alternator
To test your car’s alternator, start your engine and let it idle. Then, turn on the headlights and check if they’re bright or dim. Dim lights could indicate a problem with the alternator. To confirm, rev the engine while watching the lights. If they get brighter, your alternator might be weak. For a more accurate result, use a voltmeter. Attach the voltmeter’s red lead to the battery’s positive terminal and the black lead to the negative terminal. If it reads between 13.6 and 14.6 volts, your alternator is working fine. If it reads lower, there may be an issue with the alternator.

This can lead to symptoms like stalling, rough idling, difficulty starting, or a loss of power.
How to Check Alternator Voltage
To check the alternator voltage, you’ll need a multimeter. Start the car and set the multimeter to read the DC voltage. Connect the positive probe to the positive terminal on the battery and the negative probe to the negative terminal. The reading should be around 14 volts. If it’s much lower or higher, it could mean there’s an issue with the alternator or voltage regulator.
What Can Damage an Alternator
Several factors can damage an alternator. One is heat, which can cause parts inside the alternator to wear out faster. Electrical issues, like shorts or power surges, can also cause damage. A poor-quality or failing battery can lead to an overworked alternator. Driving through deep water can also cause alternator damage if water gets inside it.
How Long to Run Car After Jump
After jump-starting a car, it should be run for at least 30 minutes to an hour to recharge the battery. If the battery is old or in poor condition, it may require longer to fully charge. Driving the car around during this time can help the battery charge more effectively than just idling.
What Happens When Alternator Goes Out
When an alternator goes out, the car’s electrical systems will start to run solely off the car battery, which is not designed for this level of usage and will quickly discharge. Symptoms can include dimming or flickering lights, power windows, and lock issues, the battery warning light coming on, or the vehicle eventually stalling and not being able to restart.
Do Electric Cars Have Alternators
No, electric cars do not have alternators. Instead, they use a rechargeable battery pack to power the electric motor and other systems. The battery is recharged using regenerative braking and by plugging into an external power source.
Why Is My Battery Light on in My Car
If your battery light is on in your car, it generally means there’s an issue with the vehicle’s charging system, which could be a problem with the battery, alternator, or another component. It’s usually a good idea to get it checked out by a professional as soon as possible, as it could leave you stranded if your car battery dies.
How Long Can You Drive with a Bad Starter
It’s not advisable to drive with a bad starter, as it can fail completely without warning. This means your car could leave you stranded at any time. Additionally, a faulty starter can cause damage to other parts of your car’s engine, like the flywheel, which can lead to more costly repairs.
Will a Bad Starter Still Crank
A bad starter might still crank, but inconsistently. Sometimes it might work, and other times it may just click or do nothing at all. If the starter motor is weak, it might turn the engine slowly but not fast enough to start the car. In some cases, a bad starter might not crank the engine at all.
What Are the Symptoms of a Bad Alternator
Symptoms of a bad alternator can include a battery warning light on your dashboard, dimming headlights, problems with car accessories like power windows or the radio, a weak or dead battery, or even a stalling engine. In some cases, you might also notice a burning rubber smell or hear a grinding or whining noise.
