a 2000 3500 454 J motor vortec 7.4 litter
Starts hard after sitting for a acouple of hours. Has new fuel pressure regulator. Seems to be bleeding down. If you activate the key two or three times engine will start right up. If not, engine will turn over four to five seconds before firing. Assuming it is bleeding down, I'm not sure if it is bleeding into the cylanders or back into the fuel tank. Is there a test for me to determine weather I have a fuel rail problem or a fuel pump problem. Please send smart mechainic
