Hey Guys, I really need some help here. I have a 08 6.4 and I just replaced the HPFP and the truck will not start. I've bled the high pressure side until it was straight fuel and still nothing. I hooked up my scan tool and before i replaced the HPFP i was getting 400(four hundred) psi max after the replacement im only getting 3000 (three thousand) psi. I it possible i have a injector stuck open? any help would be greatly appreciated, Thanks in advanced.
