Help Me Wamba

[BRONCO JIM]

I THOUGHT I KNEW FORDS IN AND OUT, BUT THIS HAS ME STUMPED. I HAVE AN 89 FS,351W, AND THE FUEL PUMP IS HUMMING, LOUDLY. THE HUMM GOES UP AND DOWN WITH THE IDLE AND THE TRUCK IS REALLY EATING GAS. I CHANGED THE PLUGS AND THEY WERE BAD SOOTY BLACK. ALL SENSORS WERE REPLACED, ALONG WITH THE IDLE CONTROL VALVE, AND NEW EEC AND FUEL RELAYS WERE PUT IN. CLEANED ALL ELECTRICAL CONNECTIONS AND VACUUM IS OR SEEMS TO BE WORKING WITH NO LEAKS. NOW THAT IVE DONE THIS MY CHECK ENGINE LIGHT COMES ON ONCE IN A WHILE, WHEN THE PUMP STARTS HUMMING. SOMETIMES THERE IS NO HUMM, NO LIGHT, AND THE TRUCK RUNS SUPER. BAD FUEL CONTROL PRESSURE VALVE? IM THINKIN THIS MAY BE A OVER PRESSURE PROBLEM. THE PUMP IS ON THE L RAIL ALONG WITH WHAT APPEARS TO BE A LARGE IN LINE FILTER. I HOPE SOMEONE CAN OFFER SOME HELP, BEFORE I OFFER UP MORE COIN TO THE FORD GOD. WHAT IS IT WITH BRONCOS ANYWAY. CASE OF BEER TO WHOEVER HELPS ME GET THIS FIXED

BRONCO JIM had the wife re type this here,she says she will put my bed in the garage if I don t get the horse fixed soon, thanx bj

Try unhooking the battery for about 5 minutes then try it again. That will clear the computer of any codes and reset everything.

Let us know

Good Luck
