Troubleshooting Steps
If your car cranks but doesn’t start, you can follow these steps to troubleshoot the problem:

2. Check the Ignition System
Next, check the ignition system. Make sure that the spark plugs are properly gapped and that the ignition coil is working properly. You can also check the ignition module by using a multimeter.
3. Check the Electrical System
Next, check the electrical system. Make sure that the battery is fully charged and that the starter motor is working properly. You can also check the wiring for any loose or damaged connections.
4. Check the Mechanical System
If the fuel system, ignition system, and electrical system are all in good working order, then the problem may be mechanical. You may need to have a mechanic inspect the timing belt, valves, and cylinder head.
