Hello, I have an 05' dodge cummins that I just replaced the lift pump in. After priming, the truck fired up nicely and I had it idling for about 10 min. I decided to take it for a test spin. Went for about 3 miles, stopped at a stop sign, and the truck bogged (but kept running) when I proceeded from the stop sign. Ok I thought maybe air. Kept goin (had it going 60 for a couple miles) slowed to pull back into my driveway and the truck bogged (still running) when I stepped on it in my driveway. Took it for another test spin, really stepped on it and she bogged right down. Came to a stop sign, SHUTDOWN. No start. Could this be air? Injectors? Cp3? IAT sensor? Any help is appreciated.

 

and check engine codes?

 

What lift pump did you put in? is there still the in-tank pump?
