How do you reset a fuel pump relay switch?

Answered by Frank Schwing

To reset a fuel pump relay switch, follow these steps:

1. Locate the fuel pump shut-off switch: The fuel pump shut-off switch is usually located in the trunk, near the driver’s side rear wheel well, or under the dashboard on the passenger side. It may also be labeled as the inertia switch or the emergency fuel shut-off switch.

2. Switch off the ignition: Before resetting the fuel pump relay switch, it is crucial to switch off the ignition. This ensures that no power is being supplied to the fuel pump.

3. Find the reset button: Once the ignition is off, look for the red reset button on top of the fuel pump shut-off switch. It is typically small and may be recessed or covered by a plastic cap. Remove any covers or caps to access the reset button.

4. Press the reset button: Using your finger or a small tool, press and hold down the reset button firmly for a few seconds. This action resets the fuel pump relay switch and allows it to resume normal operation.

5. Switch on the ignition: After releasing the reset button, switch the ignition back to the “start” position. This will provide power to the fuel pump and allow it to function.

6. Switch off the ignition again: Once the fuel pump is re-enabled, switch off the ignition for a second time. This step is necessary to ensure that the reset process is complete.

7. Attempt to start the vehicle: After switching off the ignition, try starting the vehicle. If the fuel pump relay switch was successfully reset, the engine should start without any issues.

8. Repeat if necessary: In some cases, the vehicle may not start on the first attempt. If this happens, repeat steps 1 through 4 to reset the fuel pump relay switch again. Trying the reset process multiple times can often resolve any lingering issues and get the vehicle running.

It’s important to note that the process described above is a general guideline. The exact steps and location of the fuel pump shut-off switch may vary depending on the make and model of your vehicle. Therefore, it’s always recommended to consult your vehicle’s owner’s manual for specific instructions pertaining to your particular vehicle.

In my personal experience, I had to reset the fuel pump relay switch on my car after a minor accident. Following the steps mentioned above, I was able to successfully reset the switch and start my vehicle again. It’s a simple procedure that can be done by most car owners, but if you have any doubts or concerns, it’s always best to consult a professional mechanic for assistance.
