How do you check to see if the fuel pump on a 1989 Lincoln Town Car is bad?

Answer 1

FIRST VERIFY THE FUEL PUMP CUTOFF SWITCH DID NOT POP. IT IS LIKE A CIRCUIT BREAKER THAT POPS IF AN IMPACT JUST OCCURED, IS IMMINENT OR YOU JAM ON THE BRAKES AND THE CAR SLOWS DOWN TOO RAPIDLY. THE UNIT IS DESIGNED TO CUT OFF THE FUEL TO MINIMIZE THE RISK OF A FIRE BY SHUTTING OFF THE FUEL FLOW. THE RELAY IS IN THE TRUNK/CARGO COMPARTMENT, ON THE DRIVERS SIDE, JUST TO THE LEFT OF THE LEFT SIDE DECK LID (TRUNK) IT IS SOMETIMES COVERED BY THE GREY FELT TYPE MATERIAL THAT SURROUNDS THE CARGO AREA. IT SHOULD BE NOTED THE BUTTON TO THE RELAY IS ON THE TOP END AND SOMETIMES HAS AORANGE OR WHITE TOP. TO RESET THE FUEL PUMP RELAY, JUST PRESS IT DOWN TOWARDS THE FLOOR. THEN TRY TO SEE IF THE CAR WILL START. IF IT DOES, THAT WAS YOUR PROBLEM, IF IT DOEAS NOT START, THERE IS ANOTHER RELAY UNDER THE HOOD, NEAR THE WASHER FLUID CONTAINER, THERE ARE 2 PLASTIC COVERINGS WITH RELAYS UNDER THEM, TRY TO SWAP THE RELAYS WITH EACHOTHER THEN SEE IF IT STARTS, IF IT DOES, NOW YOU KNOW THE RELAY WAS BAD. YOU SHOULD ALSO HEAR A SLIGHT WHINING SOUND FROM THE GAS TANK MOUNTED PUMP, FOR ABOUT 2 TO 4 SECONDS WHEN YOU FIRST TURN ON THE IGNITION. IT THEN CYCLES OFF UNTIL THE CAR IS STARTED. YOU CAN HEAR IT BETTER IF YOU HOLD A LARGE SCREWDRIVER TO THE FILL HOLE, WHILE ALSO HOLDING THE HANDLE OF IT TO YOUR EAR, ALL WHILE SOMEONE ELSE TURNS ON THE IGNITION. GOOD LUCK!
