Engine Cranks but Car Won’t Start
If your engine cranks but your car won’t start, there are a few possible causes. The most common causes are:
- A dead battery
- A faulty starter
- A problem with the fuel system
- A problem with the ignition system
Troubleshooting a Dead Battery
If your battery is dead, you will need to jump-start your car. To do this, you will need a set of jumper cables and another car with a working battery. Connect the red (positive) cable from the good battery to the positive terminal on your battery. Then, connect the black (negative) cable from the good battery to the negative terminal on your battery. Start the good car and let it run for a few minutes to charge your battery. Once your battery is charged, you should be able to start your car.
Troubleshooting a Faulty Starter
If your starter is faulty, you may hear a clicking sound when you try to start your car. This sound is caused by the starter solenoid engaging, but not being able to turn the engine over. To test your starter, you can use a voltmeter to check for power at the starter terminals. If there is no power at the starter terminals, then the starter is faulty and will need to be replaced.
Troubleshooting a Problem with the Fuel System
If there is a problem with your fuel system, your engine will not be able to get the fuel it needs to start. There are a few possible causes of a fuel system problem, including:
- A clogged fuel filter
- A faulty fuel pump
- A leak in the fuel line
To troubleshoot a fuel system problem, you can start by checking the fuel filter. If the fuel filter is clogged, it will need to be replaced. You can also check the fuel pump by listening for a humming sound when you turn the key to the “on” position. If you do not hear a humming sound, then the fuel pump may be faulty and will need to be replaced.
Troubleshooting a Problem with the Ignition System
If there is a problem with your ignition system, your engine will not be able to get the spark it needs to start. There are a few possible causes of an ignition system problem, including:
- A faulty spark plug
- A faulty ignition coil
- A faulty distributor cap
To troubleshoot an ignition system problem, you can start by checking the spark plugs. If the spark plugs are fouled or damaged, they will need to be replaced. You can also check the ignition coil by using a voltmeter to check for power at the coil terminals. If there is no power at the coil terminals, then the ignition coil may be faulty and will need to be replaced.

If your engine cranks but your car won’t start, there are a few possible causes. The most common causes are a dead battery, a faulty starter, a problem with the fuel system, or a problem with the ignition system.
