RE: 2001 dodge ram starting problems
all right, I thought i had this fixed but it is still starting like crap, I have done a fuel pressure test and the system holds pressure for about 10-15 minutes and then bleeds down to nothing, and with the gas smell when it starts i was thinking it was an injector leaking so i tested them with the truck running by pulling the connector of each one and listening for changes in the motor but really didn't notice any serious changes, so then we checked the resistance and they all seemed within range of the haynes manual spec.
My questions are should the fuel system hold pressure longer than the 10-15, the only way to get the truck to start is to put the throttle to the floor if it was a sensor which would be the most logical place to start iat, map, tps, engine temp? or is there a way to pressure test the injectors to see which one might be bleeding down. Or a way to test the pump to fuel rail section of the fuel system the fuel pressure guage i have just threads on to the schrader valve on the fuel rail.
I am so puzzled by this because the truck runs and idles fine once it starts.
Any help please
