1994 Oldsmobile Cutlass Repair Question
Asked on March 17, 2008
1994 Oldsmobile Cutlass fuel pump isnt getting any power
I already replaced the fuel pump, and the relay. There is power to the relay, but no power from the relay to the pump. Cannot find a fuse, or impact safety switch anywhere. Don't know source of the higher amp voltage that comes out of the relay and to the pump.
thanks

There's 17 fuses in your vehicle and there's no fuel pump fuse listed-Dunno if the ECM B fuse is being used-
The PCM energizes the F/P relay till it de-energized within 2 secs-when the engine is being crank and oil pressure is built up this is where the OPSU powers the pump.
The fuel pump relay is nothing but a primer in that 2 secs-also see below. You're probably wondering about the fuse below-
Check for power at pin 85 coming from the computer
