- Check the fuel pump to ensure it is functioning properly and delivering fuel to the engine.
Fuel Filter:
- A clogged fuel filter can restrict fuel flow. Inspect and replace if necessary.
Fuel Injectors:
- Ensure the fuel injectors are functioning properly and delivering fuel to the cylinders.
Compression:
- Low compression in one or more cylinders can prevent the engine from starting. Perform a compression test to check the cylinder pressure.
Timing:
- Incorrect timing can cause the engine not to turn over. Verify the timing belt/chain is installed correctly and the timing marks are aligned.
ECU (Engine Control Unit):
- The ECU controls many aspects of the engine's operation, including fuel injection and ignition timing. If the ECU is faulty, it can prevent the engine from starting.
