Re: fuel delivery problems '88 xlt
Couple days ago I couldn't shut mine off, the fuel pumps kept going after I shut the engine off. Anyway check the inertia button on the inside firewall upper left of the steering column and make sure its in the down position. Check the fuel pump sending relay, its on top of the left fender well (thats where mine is) and tap it, it could be faulty, its got a black cover over it. I have an 88 F150 also. If you have two fuel tanks, there is a fuse under the dash on the fuse panel. Single tanks don't have one.
