FUEL PUMP NOT WORKING

1991 Chevrolet Corvette

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.
