The fuel pump on my '88 LX(5.0) continues to run after I turn the key OFF. It happens most of the time but not all of the time. I have to disconnect the battery which is really getting old. I had to replace the fuel pump a month ago but didn't notice anything until about a week ago so I don't think I crossed the wires but I guess it is a possibility. Is there a relay somewhere which can go bad or is it possibly from the ignition switch?

Yes, there is a fuel pump relay and also an EEC relay. They sort of work in series since the EEC activates the fuel pump relay. I believe they are located under the dash. I have to be honest, since I've never had to mess with them in my '91, I'm not sure where they are on the car. In my Explorer they are under the hood in the Power Box.

Sort of an amusing story, but the relay is under your driver's seat.
