1. Ignition switch: The ignition switch may be faulty, preventing the electrical current from reaching the ignition coil and injectors.
2. Distributor cap and rotor: The distributor cap and rotor may be worn out or cracked, causing the electrical signal to be interrupted.
3. Ignition coil: The ignition coil may be faulty, preventing the electrical current from reaching the spark plugs.
4. Fuel pump: The fuel pump may be faulty, preventing the fuel from reaching the injectors.
5. Fuel filter: The fuel filter may be clogged, preventing the fuel from reaching the injectors.
6. Fuel pressure regulator: The fuel pressure regulator may be faulty, preventing the correct fuel pressure from reaching the injectors.
7. Wiring harness: The wiring harness may be damaged, causing the electrical signal to be interrupted.
8. Engine control module (ECM): The ECM may be faulty, preventing the electrical signal from reaching the ignition coil and injectors.
Additional information:
* If the engine cranks but doesn't start, the problem is likely related to the ignition system or fuel system.
* If the engine cranks slowly or doesn't crank at all, the problem is likely related to the starter system or battery.
