update

i did all the grounds and added some more , and cleaned everything . now i have no codes , but the truck still won't runn . i cracked open the injector line and i have no pressure there , so does that mean CP3 is no good ??????? is there a way to check it ? are any other things i can try , i do have lift pump pressure at the cp3 . just no high pressure at the injectors just about the same as lift pump pressure

Not sure about CR diesels, but doesn't the regulator in the fuel rail control pressures?

I remember reading something about FCA rail adapter or something like that?
