Well I installed Marks 3794 Stg2, new cp3, deleted the EGR and my truck aint happy. After I got everything installed I loaded a tune that had a no start tune in one of the DSPs(zeroed out inj. quantities). So I could crank the engine over to prime the turbo with oil and get some fuel through the CP3. I had also removed the maxfuse for the Grid Heater.
When I tried to turn the engine over it wouldn't crank. It just clicked and the headlights, dash lights (CEL, Glow Plug), RV mirror light, and radio all started flashing. The ABS pump under the cab started pulsing and other things too. I got 4 codes P0540(Grid Heater), P0405(EGR Low Voltage), U1026(Lost Com. Tcase), U1041(Lost Com. Brake/Traction Controller). I've had the EGR blocked and haven't gotten an EGR code ever.
I thought maybe pulling the maxfuse was the problem and reinstalled. Never got the 2 Lost of Communication codes again, but still no crank and all the flashing. Still getting the other 2 codes. (Edit looks like when I switched off the Grid Heater CEL it didn't save in the tune so I still need to reload the tune to see if that fixed that code). I looked over all the plugs I could see without tearing anything off and everything looks ok. I tried plugging back in the grid heater (not the big power wire) and EGR and that didn't change anything.
I'll pull a few thing off in the morning to get a better look at all the wiring harnesses. I can't see that any of the plugs could be in the wrong place they all looked to be unique. Never did messed with anything from the Tcase or Brake controllers, so I'm not sure whats going on there. The only ground I removed was the one to the hood and its still off, but I doubt that's the problem.
The ECM is flashing fine, so I didn't brick it. I guess it could be the no start tune. Its been so long since I built it I don't recall if the engine cranked or not. I pretty sure it did. I might load another tune what do you unplug to get the truck crank and not start? Crank sensor? Any other ideas?
