In this article, we will explore the abbreviation of the fuel pump relay of the GS4 and its related issues.

1. What is the abbreviation of the fuel pump relay of the GS4?

The abbreviation of the fuel pump relay of the GS4 is FPR (Fuel Pump Relay).

2. How does the FPR work in the GS4?

The FPR is responsible for controlling the fuel pump of the GS4, which delivers fuel from the tank to the engine. When the ignition switch is turned on, the FPR receives a signal from the engine control module (ECM) and activates the fuel pump. If the FPR fails, the fuel pump will not work, which may cause the engine to stall or fail to start.

3. What are the symptoms of a faulty FPR in the GS4?

If the FPR of the GS4 is faulty, the following symptoms may occur:

- Engine cranks but does not start

- Engine stalls while driving

- Fuel pump does not turn on when the ignition switch is turned on

- Check engine light is illuminated

4. How to diagnose and replace a faulty FPR in the GS4?

To diagnose a faulty FPR in the GS4, a mechanic may use a scan tool to check for diagnostic trouble codes (DTCs) related to the fuel system. If a code related to the fuel pump relay is detected, the mechanic may test the relay and wiring to confirm the problem. If the FPR is confirmed to be faulty, it needs to be replaced with a new one.

Conclusion

The FPR is an important component of the fuel system in the GS4. If it fails, the engine may not start or stall while driving. Therefore, car owners should pay attention to the symptoms of a faulty FPR and have it diagnosed and replaced in time to ensure the normal operation of the vehicle.
