mack mp8

After the problem they took out everything (the stereo, speakers, etc). my friend checked everything out and fixed a lot of electrical stuff.but The engine starts but it doesn't respond when you push the accelerator , additionally it doesn't turn off when the switch is moved to off. I am wondering if anybody has a diagram of the truck or the diagram of the ecm. I would appreciate it alot, thank you. My email is

I can see if I can manage to pull em out of the 'puter tommorrow. what year ? The newest wonderful version has a radio that MUST be programmed by a dealer .......isnt that wonderful?have to see if any news of aftermarket install issues, I personally have not encountered that yet. If the throttle isnt responding you have J1939 communication issues. Unfortunately w/out a laptop and PTT subscription you cant get far w/this piece of ......................(.machinery?)If it has the LCD dash cluster and full function diag. stalk ( on r/s of column) you should be able to at a minimum pull out codes.That will be a start, but these new dogs are like working on cars! they've got ECU's tellin ECU's the driver may need to pass gas Either way it may be tommorrow night before I'll be able to give you a response
