Had it towed, went back next day and it started right up. Replaced relay. A week later, it won't start again. Don't the in tank fuel pumps usually just quit? Is there an inertia switch I should check? Thank you!

Thoughts:

. Check all under-dash and under-hood fuses with a test light or multimeter:

. Check for codes.

. Reset ECU.

If you hear the fuel pump run, when the ignition switch is turned to ON, then it is likely okay. Have you changed the fuel filter recently?

GM pumps do have a tendency to just up and quit one day without any warning. As far as I know, they don't have an inertia switch but I could be wrong. Have you checked for both fuel pressure and spark?

Check for power both to and from the pump. I once saw a Yukon with no fuel pressure and obviously, everyone thought the pump had gone out. The customer authorized the repairs but when we went to take it apart, we found a broken wire. As soon as we repaired the wire, the truck fired right up. Odds are it's the pump, but it's always best to rule out everything :)

Would you be talking about the wires running to the fuel pump. I have a 98 that killed on me while rolling down the highway and won't start back up. Tried starting fluid and it's a no go.
