2020-22 Duramax 3.0 Long Crank No Start


Recommended Posts

Trying to decide whether to keep or trade this 2021 1500 RST Duramax that intermittently won’t start. Are any of you with the PIP5823b ECM update still having starting issues? I really appreciate your input.

Lots of 'successful' relies in all the others threads on this subject. 

Both on this forum and on other dmax forums.

Had PIP5823b done on 4/8 and had a long crank no start on 4/12 in very rural N Georgia late night. Cranked 20 mins later. I’m going to pursue buyback or trade for similar RST V8 or a RAM diesel. I’m sick of the stress of a possible no start every time I push the button on a new $50k vehicle.
