ive also seenthat on cummins forum but none of that fixed it

 

I mean completely disconnecting it bro, not just switching to stock settings.

 

yeah sorry ive had the smarty totally off my bad it still does it though i put electric grease on the ecm plugins yesterday now i just have to wait for it to get cold but i heard it could be anything from the lift pump to the ecm so far and i wish someone could narrow it down a little more but we will have to wait and see

 

how about the Air Temp Sensor crapping out. That tells the ECM how cold it is, and the ecm controls other functions based on air temp. Just tossing out another one......

 

so sick of this issue i brought it in and they couldnt figure it out either so thats always nice

 

re tighten the injector tubes that go into the head, I had the same issue a while back and we found one of the injector tubes loose just took a half turn and then it went a way, I replace lift pump fca blue out lines. to find out it was the cheapest fix of all.

 

You missed it some where in the ecm power circuit. Check that circuit like a CSI. Wiggle test.
