Codes

OK I got codes.
P2291- Injector Controll Pressure too low
P2614- Camshaft Position Output circuit/open
P2617- Cranshaft Position Output circuit/open

Anyone had all these codes come up? I've had issues in the past with no codes coming up on the dash. The wife took it up to take the little one tothe drs and when she came out it wouldnt start. it turned over but no start. She put the pedle to the floor and she started up and came home. I came home put the reader on and it gave me those codes. I started it up and it was fine.

Ignore P2614 and P2617. That only means that the PCM lost cam and crank sensor inputs due to the engine stalling, or in this case, the engine not starting.

P2291 is ICP too low while cranking. This means the PCM didn't "see" sufficient ICP (Injector Control Pressure) at the time your wife tried to start the vehicle, which was the cause of your no-start symptom. Being an '05 model year, I attribute a leaking STC fitting as the most probable cause of your issue.

What is the STC fitting? And where is it?

Thanks

STC fitting = Snap-To-Connect fitting

This is the fitting located at the outlet side of the high pressure oil pump. It's purpose is to supply high pressure oil to both banks of cylinders through what's called a branch tube, in order to operate the injectors.

Due to its inevitable failure, it has been updated to a one-piece fitting, thereby eliminating any possibility for repeat failure.

If your truck is still under warranty, this is a covered repair. There was also a TSB outlining the complete diagnosis and repair of this concern. It has since been supersceded to following WSM instructions.
