No 5v Power From ECM

No 5v Power From ECM
Does anyone know why I would not have 5 Volt power or power to my fuel pump relays coming from my ECM? Pins 48 and 50 have a 12 volt supply and pin 49 appears to be a good ground.
This is an '02 24 valve 5.9 with the manual six speed. It has an Edge Juice Tuner. The engine was transplanted into this 80's Chevy truck several years ago by someone else who I do not have contact with. The PCM is bypassed. The truck was running fine on the 30 minute drive to pick up my trailer. I shut it off while I connected and then it would not restart. The engine will run if the lift and injection pumps are hotwired. The Cummins Bus pin 2 (+) is supplying 4.2 volts. The Cummins Bus pin 12 (-) is supplying 1.2 volts. Both busses are now supplied through the edge.
Thanks
