How do you test the fuel pump relay on a 1993 Chevy 1 ton Beauville van?

To test the fuel pump relay on a 1993 Chevy 1-ton Beauville van, first locate the relay in the fuse box under the dashboard or the engine compartment. Use a multimeter to check for continuity by removing the relay and testing the terminals; you should get a reading when the relay is activated. Alternatively, you can swap the relay with a similar one in the fuse box to see if the fuel pump operates, or apply power directly to the relay terminals to check if it clicks and engages. If the relay fails any of these tests, it should be replaced.
