- Inspect the fuel pump for any signs of damage or wear.
- A defective fuel pump can cause insufficient fuel pressure, leading to stalling.
2. Clogged Fuel Filter:
- A blocked fuel filter can restrict the flow of fuel to the engine.
- Check the fuel filter and replace it if necessary.
3. Faulty Fuel Pressure Regulator:
- A faulty fuel pressure regulator can cause incorrect fuel pressure, resulting in stalling.
- Inspect the fuel pressure regulator and replace it if needed.
4. Defective Oxygen Sensor:
- A faulty oxygen sensor can provide incorrect information about the air-fuel mixture to the engine control module (ECM).
- This can cause the ECM to adjust the fuel mixture incorrectly, leading to stalling.
5. Ignition System Issues:
- Faulty spark plugs, ignition wires, or distributor cap/rotor can cause ignition problems and result in stalling.
6. Vacuum Leak:
- Vacuum leaks can lead to a lean air-fuel mixture, causing the engine to stall.
- Check for vacuum leaks and repair them as needed.
7. Faulty Idle Air Control (IAC) Valve:
- A faulty IAC valve can affect idle stability and stalling.
8. Engine Control Module (ECM) Issues:
- Problems with the ECM can lead to various engine issues, including stalling.
- Have the ECM scanned for any trouble codes and address any malfunctions.
