I have a 1/04 6.0 with 140k that will not start hot. I replaced all injectors today ,2 had the top o rings cracked, put new plugs in the oil rail, new p/u tubes and new rear plugs. I also did a egr delete. Are the oil branch tube servicable to the hpop, i put in new standpipes or is it the hpop?? Or if the ipr failed it would give a code or not run at all?

 

Search for STC (snap to connect) fitting.

 

Thought that was on the 05's.

 

It was the irp valve

 

glad you got it figured out those 6.0 leakers can stump even the best of mechanics
