Code P0342, after I finally got all other code fixed, this one pops up.

What is your question?

OK, so I have this truck with an initial issue of a faulty fuel pump, improper fuel read on gauge and no oil pressure. I replaced the fuel pump/sender and the oil pressure switch. Those are both fine and now work great. But, now I have this new P code pop up. I have replaced the CMP with a BWD part from Oreillys. This didn't fix it. Looked deeper found a few wires on the CMP plug were peeled back and touching each other. Taped these up, reset the comp and it was great until after about 30 miles when it started over with the code again. The pins and the socket terminals look and feel fine (not ruled out yet) but eyeball looks good. Truck will idle and run great, drives all day no issues. It is hard to start and sometimes it sounds like an engine that has hydra-locked (this is the best way i can decsribe the symptom ). This will happen for about three attempts to start then it will finally start. What I can see of the reluctor wheel the teeth are fine and no obvious signs of contact with the sensor itself. (just to rule out) When scanned with a 2014 Verus D10 series scanner, the codes only pull p0342 under the drive line. Looking into the system a bit deeper, the ABS system pulls a code also, c0550. That code shows an ECU/CCU Malfunction. Is this a stand alone subsidiary ecu or is it part of the main ecu. If it is internal would this point to the main ecu as faulty and thus demand a replacement? I have not ruled out the terminal contacts at the ecu yet, so I understand this still needs to be done. But, So far I have to start leaning to the ECU. This truck was driven at least 50k miles with the initial issues before they were looked at and corrected. The previous known repairs have been, repairing/replacing a broken/cracked bell housing and the transfer case busted off the tail housing coming to rest on the cross member (signs of heavy wear at the crossmember-not sure how it was driven in this condition). The front wheel was about to fall off due to poor ball joints and the outer tie rod end loose. Not sure if ALL this vibration chaffed some wires or simply knocked these systems out directly. Either way it is not good. I know this a lot of information but i just want a good solid educated opinion before I proceed to ECU replacement/reflash.
