The truck kept throwing an ecm failure code, after replacing the vp44 and an upgraded fuel system it still wouldn’t start. They originally sent a pcm so I ordered an ecm and just left the new pcm on. The company was car computer exchange. I’m starting to think it’s not programmed right.

2002 cummins 2500 6 speed H.O. I need help a few weeks ago I was driving and lost fuel pressure, truck would barely idle and would cut out at 1500 rpm. I made home and it died, I have put a new ECP, PCM, vp44 and installed an air dog fuel system, new map sensor and intake temp sensor. I have been chasing wires everywhere and I haven't found a break or rub through yet. The codes im getting are p0237 turbo boost sensor circuit low, p0237 boost pressure test failed, p1689 EGR actuator control circuit low negative side, p0112 IATS 1 circuit low bank 1, p0237 turbo boost pressure sensor circuit low ( its showing 4.98 volts), I don't know where to go from here! My older code reader says no communication between ECM and injection pump. Any help would be greatly appreciated.
