I kind of got the same problem going on, went to start nothing. Towed it into town started. Went to start it couple days later nothing. Jump the plug by right battery starter turns. When key is turned to run no glow plug light, no fuel pump prime. Tested ignition switch good. Tried 2 new Batteries nothing. got power on fuse 52, continuity from fuse 52 to pcm connector. Fuse 49 and 50 also have power. Scan tool will not communicate with pcm.
Codes after cleared:
instrument cluster
uo100 lost communication to pcm
u300a-64 ignition switch...
transmission:
u0294 lost communication with pcm
Body control module:
u0100-87 lost communication with pcm
B10f1-14 key in switch short to ground or open

 

U codes as you can see are communication errors. I would check all electrical connectors on major components such as the BCM, PCM, TCCM, etc to see if any are not making good connection. I would even consider unplugging them and spray with WD-40 and reconnect.

All three point to the PCM as maybe where the connector might be giving the problem. Check under the hood for the 3 connectors on the passenger side near the air conditioner to see if they might be the problem. That is the PCM in that location.

 

And maybe start a new thread as this one is 5 years old. You may get more help that way.

 

I have read where there is a large wire harness connector that is connected to the parking brake pedal bracketery up under the dash, that may come loose after a while and cause havoc with all the electronics. It might be worth checking, especially if you use the parking brake a lot. If it turns out to be the culprit, attaching it elsewhere seems to remedy the problem.
I am thinking that this has been primarily gas powered trucks, but might be a possibility in the diesels, also.
Good luck to you!

 

thanx but I tried that even the connector on transmission and nothing

 

Hey Gaut,

Don't have any words of wisdom about your issue, but I moved it into its own separate thread. Your issue is completely different than the sensor issue that happened in the thread you posted in.

 

Yeah, I've tried reseating all the connectors on pcm nothing happened. Ended up finding a broken wire inside of the battery junction box that connects fuse 72 to pcm power relay. repaired the break and started up no problem. Thanx guys
