1998 Olds LSS no fuel pump
My son'* 1998 Olds LSS 3.8L ran fine, started it up in the morning, and ran for 5 minutes and quit. Started again in the afternoon ran fine for 5 minutes then quit again. Started checking it out, no fuel in the fuel rail. Fuel pump won't cycle on key switch. Pump relay and fuse are good. I can't get power at the connector above the fuel tank going to the pump. Security light is out, and the engine cranks over. Have spark at the spark plugs. May be coincidence, but the power window quit at the same time. Can't find any blown fuses in any of the 3 fuse boxes, and swapped out relays 1 at a time with a known good relay. Still no fuel pump operation.
Put new fuel pump in because I had one, still won't run.

Thanks to Mike I got it. Cleaned both ground busses, and everything is working again.
