Troubleshooting a car engine that doesn’t start

Check the battery voltage. A battery that is too weak to crank the engine will need to be replaced.
Test the starter. If the starter is not engaging, it may need to be replaced.
Check the ignition switch. If the ignition switch is not sending power to the starter, it may need to be replaced.
Inspect the fuel system. Check for leaks, clogs, and other problems that could prevent fuel from reaching the engine.
Look for electrical problems. Check for loose or damaged wires, blown fuses, and other electrical issues that could prevent the engine from starting.

Additional tips for starting a car engine that doesn’t start

Try jump-starting the car. This can be done by connecting the battery of another car to your car’s battery.
Try tapping the starter with a hammer. This can sometimes jar the starter loose and allow it to engage.
Try rocking the car back and forth. This can sometimes help to free up a stuck starter or fuel pump.

When to call a mechanic

If you are unable to start your car engine after troubleshooting the problem yourself, it is best to call a mechanic. A mechanic will be able to diagnose and repair the problem quickly and efficiently.
