WILL A BAD FUEL PRESSURE VALVE PREVENT THE FUEL PUMP FROM WORKING?
I HAVE PERFORMED REGULAR TUNE UPS ON VEHICLE SINCE NEW.
THE VEHICLE WAS STORED OUTSIDE FOR 4 YEARS. THE TRUCK
WOULD CRANK NOT RUN. I REPLACED THE BATTERY. I CHECKED THE
FUEL RELAY OKAY. INERTIA SWITCH OKAY. FUEL FILTER OKAY. I
DEPRESSURIZED FUEL SYSTEM TO CHANGE FUEL FILTER. THE
TRUCK WILL RUN WITH STARTING FLUID BUT NOT WITHOUT. PLEASE
HELP
