First I appreciate letting me in this forum. I have been turning wrenches my entire life. I found sometimes it more efficient to ask for help up front.
Driving in this morning, loss of engine power. Dash lit up. Pulled over (had no choice as it quit). Everything was flashing. Flashers would work but headlights would not even come on. OBD reader said it could not communicate. Saw smoke from under the hood. I opened it and found diesel everywhere. Very bad on driver's side. My first thought was one of the lines came off the plastic water Seperator but that does not look like the case. The electrical issues are because everything is covered in Diesel. I'm lucky it did not catch fire. Got it drug back home and will look at it when I get off work. It was still dark. Ill degrease and wash it all off and look for a leak. Fuel Pressure O Ring? I have a new billet Seperator that I have been waiting to put on.

Sorry my friend.
My stepdad had a similar situation a few years back. 1 battery was shot in his 2015 Cummins, stranded us at lunch one time. Got 2 new batteries and truck fired up like nothing. Batteries were “only” 4 years old I believe. Unfortunately these days batteries are just a consumable like a fuel filter.

Agree with @Calif250... Now 4 weeks after post. If you cranked Engine several times trying to start before performing 3-5 Prime cycles, the CP4 cycled dry for a lengthy period.

I'd be planning hard & fast to avoid a CP4 disaster taking whole fuel system out!

I'd examine an SPE or S&S DPK (Desaster Prevention kit) asap. The S&S is popular, I personally like the new design of the SPE DPKv2 kit. Both do the job to prevent a costly $10K-14K repair.

Best of Luck to ya!
