1. Faulty Fuel Pump Relay:
- Even though you replaced the relay, there is a chance that the new relay is also faulty or not properly installed. Double-check the relay connection and ensure it is seated correctly.
2. Fuel Pump Circuit Issues:
- Check the wiring leading to the fuel pump. Look for any damaged, loose, or corroded wires. Ensure proper continuity in the circuit by performing necessary tests.
3. Fuel Pump Fuse:
- Inspect the fuel pump fuse to ensure it is intact and functioning properly. A blown fuse may disrupt the power supply to the fuel pump.
4. Fuel Pump Check Valve:
- Verify if the fuel pump's check valve is stuck or faulty. A malfunctioning check valve can cause fuel pressure to remain high, leading to continuous fuel flow.
5. Fuel Pressure Regulator:
- A faulty fuel pressure regulator can disrupt the fuel system's ability to manage the fuel pressure, resulting in an improper fuel flow and pump operation.
If you are not experienced in car repairs, it's recommended to seek assistance from a professional mechanic who can diagnose the specific root cause and address the problem safely and effectively.
