truck cut off while driving and won't start back up
I was driving and the truck cut off. it was like I ran out of gas. I though that the safety switch tripped so I checked that and it was ok. I sprayed starting fluid in to the intake and it starts but cuts off as soon as the fumes are gone. when I turn the key on I can hear the fuel pump running and I put a new pump relay on it. there is a valve at the end of the fuel rail when I open that valve with the key on fuel shoots out so I know that I am getting fuel to the fuel rail buy its not getting to the engine.
Well, we do not know what year truck you are driving, but moderate age trucks with injection have a test port on the fuel rail. I do not suggest to defeat the mechanism on the rail as fuel will shoot out all over the place. If you suspect the fuel pump, purchase a test gauge and test the pressure properly. A decent one is about fifty bucks.
