How do you check fuel pump relay switch?

To check the fuel pump relay switch:

1. Locate the fuel pump relay. It is usually located in the engine bay, near the battery.

2. Remove the relay from its socket.

3. Inspect the relay for any signs of damage, such as cracks or burns.

4. Shake the relay to see if it makes any noise. If it does, it is likely damaged and needs to be replaced.

5. Reinstall the relay in its socket.

6. Turn on the ignition.

7. Listen for the fuel pump to run. If it does not run, the relay is likely damaged and needs to be replaced.

Note: If the fuel pump does not run, it is also possible that the fuel pump itself is damaged or that there is a problem with the wiring. If you are not sure what the problem is, you should take your vehicle to a qualified mechanic for diagnosis.
