The saga continues. Last night i pulled the front back off the front of the motor and started from 0 and redid the ip gear set up. Put the truck back together and no change, Still no start. I do not understand what the deal is. I replaced the ip, pmd, glow plugs, harness . Checked the grounds . Nothing. I do not understand the electronics on this nor how to set the timing if it wont run. With the gmtd scan hooked up it shows timing at 14 . i dont know what that means. i am not able to change that. Crank it and it bounces around but not by much. Move the pump and restart, value is the same. At this point I think i may cut bait and put my mech pump on it and use the trans and controller from the dually. I really dont want to pull the motor and put it into the dually , still may . All I know for sure is I'm not pleased with my performance and i hate the electronics. Sorry for the rant.
