10

Asked by shawnofthedead Mar 07, 2014 at 03:15 PM about the 1989 Ford F-150 XLT Lariat Standard Cab 4WD SB

Question type: Maintenance & Repair

I have a 89 ford f150 xlt lariat. Has a
5.0 302 v8 efi motor. The other day i
was driving and my truck just died.
Wouldn't start up again. I got home
and turned the ignition to the
"On" position and no fuel pump
sound. So i jump the fuel pump from
my battery and it runs. But won't run
when not jumped. So I replace the fuel
pump relay and eec relay. Still
nothing. I checked the inertia switch
and its not tripped. Last thing I can
think of is something in the wiring.
Need some help.

been thru this same list of problems. found that ford used two different fuel pump relays, one 4 pin and a 5 pin. wont interchange.. low fuel pressure caused buy high pressure pump failure causes same problem. runs but dies. so check fuel pressure then make sure . mine needs 40 psi to run.

Similar thing happened to me I tested everything fuel-related from inside the tank to the injectors it turned out to be the Tif on the side of the distributor they overheat and act out way before they quit completely.
