Isnt that the regulator?
The one on the rail is pressure relief. I think they are two different things.
Yes, they are....
FPR = Fuel Pressure Regulator (on CP3)
FPRV = Fuel Pressure Relief Valve (on fuel rail)
OP, please fill out your sig so we know what truck you have and any mods.
That being said if it's an LLY try ice picking your injectors and reinsulating the FICM harness at the alternator bracket.
