04 GMC Sierra 4.3 NO START! GOT FIRE AND FUEL TO THE TOP
04 GMC Sierra Got spark at plugs when cranked got aftermarket fuel pump cause truck has air ride and needed aftermarket fuel cell been running fine for months. Pulled out of driveway after jump starting another vehicle and it shut down.
HAS SPARK
HAS PLENTY OF FUEL PRESSURE ALL THE WAY TO THE INTAKE
WONT START.
CHECKED PRESSURE GOOD
CHECKED ALL FUSES GOOD
CHECKED FOR CODES NON
WILL START IF DUMP FUEL INTO INTAKE. but injectors dont fire.
Originally pump would not come on through stock wire harness.
so i straight wired it still no go.
IS THERE SOMETHING THAT SHUTS PUMP DOWN AND DOES NOT ALLOW INJECTOR PULSE? I NEED REAL HELP
