Fuel pump stays on

The fuel pump on my 1990 Ford F150 stays on after I turn off the ignition. Is there a relay switch for the pump that would be causing this, and if so, where the heck is it?

Generally a relay, located in the left fender area. The owner's manual details the location of the relay center and that's where it probably is.

Thanks Joe.

I saw the relay in the schematic in the Chilton's manual. I needed the picture with the arrow pointing to the part, with a caption that said - "here's where it is, moron", but it wasn't there.

Today, I just went into the local auto parts store, and asked.

He said it was probably the relay, or it could have been the ignition switch. I just bought the relay for $22. The left fender has a bunch of relays, most of which looked alike. So I figured I'd reconnect the battery, and just start unplugging some until the fuel pump went off. Dumb luck - it was the very first one.

Works fine now.

Thanks again for replying.

Good job.

Mark it with a Sharpie permanent marker so you know for next time .
