1991 CORVETTE FUEL PUMP NOT WORKING

  • Tiny
  • Lsc5spd
  • 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.

Do you
have the same problem?
Yes
No
