Hey there scotty im new on here buti havea question for you i have a Gmc Envoy xl that crank but won't crank.I change the fuel pump about five months ago.Drove it for about two weeks and it started giving me problems I put inthe shop.And the mechanic told me.That the proms in the fuse box where fuel pump relay plugs into is not getting contract.Is that possible.And how can you repair that.Im Keith S

welcome aboard. Yes, that is possible, and on those, often the wiring going into the gas tank to fire the pump goes bad too. You can either repair that fuse box connectors, OR just bypass is all and rewire the relay outside the box, cutting the wires under the box and making new ones for the relay. I do that a LOT
