1991 Corvette fuel pump not working
FYI:
Some time ago I asked for help in solving this problem and got a response that "It was not the "oil sender" however after much trouble shooting it turned out to be a short in the wire from the 2nd oil sender switch on this vehicle that provides input to the ECM.
These cars apparently have a fail safe mode that needs a minimum of 3-4 lbs oil pressure to close a NO switch in the circuit. This enables the fuel pump relay to energize.
