I found these, I'll do some more research to see if I can help.

Code: P2510
Modules: ECM
Description: Engine Control Module Relay Circuit

Trying replacing the ECM relay, and if thats a no go, start checking the wiring, I will see if I can post the wiring diagram tommorow after work.

Awesome man thanks. One more thing... After the few times it shut down my truck... I was able to drive it but it seemed like the radiator fan was louder and turbos maybe npt spoiling like they should???? But def the rad fan was noticeably louder.

Could this be a reason that sometimes when I go to start the truck it clicks like it's dead then shut the key off and try start and it goes? Maybe cuz I've been running one battery for a month or so?

the 911 forum is for "I'm stuck on the side of the road right now" situations only. Moved this to LMM forum.

I had to replace the ECm in my truck recently for a p0335 code. Even after replacing the ECM the truck wouldnt start because tha battery in it was drained and no matter how i tried to jump it off, it wouldnt. i would try putting both batteries in and making sure they are fully charged. the radiator fan seems unrelated, but im not postive. I would start with two good fresh fully charged batteries and a new relay and go from there.

just a little update..... I found that my Positive battery cable on the pass side was against my new downpipe which melted the insulation, in turn made that shit ground out and shutdown the truck.
