Long story short, but after swapping out cp3 today. The truck wont start. No codes besides a glow plug heater circuit a. Things that are done to the truck are, fass titanium 150 lift pump, boost fooler, 45% sac injectors, 5 in exhaust, k&n air intake, and efi live with dsp5. The reason why I swapped out cp3 is due to low fuel rail pressure on any tune besides stock tune. The new cp3 is a super sport with the lbz fuel pressure regulator from LDS. Filter head is leaking but never had any issues with it not starting before today. Scanner only shows 219-254 psi for the rail. Small fuel leak on the passenger side towards the front of engine. Running down by oil filler tube, and down the top of the intake running towards the back of the head. Haven't pulled it apart yet to figure out that leak. Pulled the alternator off and didn't see anything. Any thoughts on what to try nexted before I pull it back apart?
