- A faulty fuel pump can cause intermittent starting issues, especially when the engine is warm.
Fuel Pressure Regulator:
- A faulty fuel pressure regulator can disrupt the supply of fuel to the engine, leading to stalling.
Crankshaft Position Sensor (CPS):
- A damaged or dirty CPS can disrupt the timing of fuel injection and spark ignition, leading to an immediate shut-off.
CamShaft Position Sensor (CMP) -
- A crankshaft position sensor (CPS) or a camshaft position sensor (CMP) failure can cause the engine to start and stall immediately.
Ignition System:
- Ignition-related issues, such as a faulty ignition switch, ignition coil, spark plugs, or ignition control module, can disrupt the correct spark timing and cause immediate engine shutdown.
Vacuum Leaks:
- Vacuum leaks can disrupt the air/fuel mixture, causing the engine to run erratically and stall.
Fuel Quality:
- Substandard fuel quality or the presence of water in the fuel can lead to engine performance problems and stalling.
Throttle Body:
- A dirty throttle body can disrupt airflow to the engine and affect its ability to run properly, leading to immediate shutdowns.
Computer:
- In some cases, computer issues, software glitches, or faulty sensors can provide incorrect information to the vehicle's computer, leading to starting problems.
Battery Connections:
- Loose or corroded battery connections can disrupt electrical flow and hinder the proper functioning of the engine, resulting in immediate shutdowns.
