There is a fuel pump relay that sits on the engine side of the firewall, on the driver's side of the AC unit. it has a harness going in with 5 wires, one of which is a prime connector that does not connect to anything when in running order. I don't remember all the colors, but orange is power and gray is to fuel pump.

skyler and papa are the most helpful. In the case of my 89 GMC Suburban 2500, I used the prime connector to activate a relay for twin electric fans to help cool a new radiator and suddenly both the fans didn’t run and the truck wouldn’t fire. A bit of starter fluid gave another clue (instantly fired up for a few seconds then motor died). Found a different switched lead for the twin fans and checked the ECM fuse---- visual inspection appeared intact, but being suspicious I checked continuity and it was sketch. Put in a new fuse and fuel pump came on and engine fired up as normal. Learned a few lessons here----one surprising one is never trust a visual-only inspection of a fuse for one. There are others but thanks Skyler and Papa---local mechanic was too busy for advice and I don’t blame him---glad he’s working and busy. thanks guys. JV
