Question about 1987 Ford F 150
Hi, I have a1987 f 150 302 cu in with aod trans ,dual fuel tanks. 110k miles.
I purchased it used and at first noticed it would shut off while driving sometimes being fine for 50 miles at other times it barely left the driveway. it would start back up usually after setting a couple of minutes, idle okay but bucking and stumbling , sometimes doing this for 10 mins. I replaced the ign module with a wells unit purchased at autozone. it seemed okay for awhile...... then started doing it again....Now a new problem.... the pumps will not energize after turning the key to the"on" position ( won't start), i repl the fuel pump relay and still no buzzing, no fuel pressure at the shrader valve..... the engine will run if you squirt fuel into throttle body.........HELP!
Try putting a new fuel pump in it or check the fuel tank switching unit it might have failed. (switch or unit under truck).I would go under truck and try to isolate one tank both electricaly and mechanicaly the see how it runs.
