Asked by Aug 16, 2016 at 04:08 AM about the 1989 Ford F-150 STD Extended Cab 4WD LB

Question type: Maintenance & Repair

I Got a 89 f150 supercab 5.0 with dual tanks, I've replaced
the fuel injectors, wiring, spark plugs, ignition coil, relays
and relay wiring. both fuel tanks and fuel pumps. Yet, my
truck won't start it doesn't have fuel pressure, and I
replaced the fuel pressure sensor. It's not sending anything
from the tanks. Not quite understanding as to why, I even
double checked the fuses. If anyone could help me out with
possible solutions.

1 Answer


check the switching valve on the frame. I had the mechanical one and had the same problem.
