How do I change the fuel pump relay on a 2001 Chevy 1500. It will not start, it cranks but nothing else. I hear the fuel pump running when I start it and I was told it could be the relay.

The fuel pump relay is under the hood in the relay junction box. However if you hear the fuel pump humming I doubt it is a relay problem. Have you checked the fuel pressure to see what it is. This system needs 65 psi to start and 55 when running. You could have a bad pump providing you are getting spark to the plugs.
