SOURCE: truck starts, dies. truck runs good some days,bad the next

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

remember the switch only gets power for 1 second when u turn the key on, the common problem is the ignition starter switch comes apart, it is located at top of the steering column near the bottom, drop the column down (2 nuts) and inspect the switch for separation.

You are right. There are three pumps. It sounds like the transfer pump in the front tank is bad. The in tank pumps just supply the high pressure pump to keep it primed. You need the front pump.

you should probably check your fuel pressure between the pump and the fuel bowl. my bet is that is is dropping pressure to zero causeing it to shut off just after it gets running. and there are several things that could cause that but the first to check is a return line valve on the side of the fuel bowl. that when pressure builds up it releases back into the tank and if it gets stuck open you will not have enough fuel pressure to run your truck. mine just did the same thing.

if it was me i would make sure its not the fuel pump relay give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair Manual for your SUV wish you the best of luck Michigan Man.
