Re: Sputtering Engine--Fuel Pump Problem???
Hi, I had similar problems, lousy performance from the stop light or stop sign when taking off, I would have to kind of baby it from take off. Then the fuel pumps would stay on after I shut the engine off. I found the problem myself and it was the fuel pump relay or fuel pump sending unit, whatever you want to call it. I replaced it and it was like I gave the darn truck a complete tune-up. You can get the relays at autoparts stores. Its one of the cheaper ways to try and eliminate the problem. Also you might want to change the fuel filter. Mine is an 88 F-150 and the relay is on the top driver's side inner fender well. Now later models in the early 90's may have changed the location of the relay. Some trucks may also have a fuel regulator unit and that could be giving problems, but I'm not familiar with those.
