Hi everyone, I am new here, and am in serious need of some help. I have an 04 chevy 3500 with a duramax. We have been working on this thing a year now. It has a condition of after it warms up and is shut down it will not restart. we have replaced about everything in the fuel system, injectors, pump, regulator, fprv, filter housing, and fuel lined. Still when it is no start I am only getting 800 lbs of pressure at the fuel rails while cranking. Has anyone encountered this condition. Any help would be greatly appreciated.
