Ecm or altenator issue?
Alright, first off and for most thank you for any and all reply I receive
So I have done a fair bit of Googleing and searching around, and have come up with nothing. Called cummins, called blue chip diesel, and haven't found a single person who has had the same issue happen. I have a 5 speed 99 dodge 4x4 2500 exsb, ts mvp fuel boost Pyro gauge, bhaf, s366, 150 injectors, pusher intake. When I start the truck at any time it INSTANTLY revs to 3000 ish rpm, then drops to 1000. When I push on the accelerator it will only Rev to 1800 or so, and that's it. Sounds awful and produces and incredible amount of white smoke (as in my cul-de-sac is filled as soon as the truck finishes going to 3000 rpm) I have never tried to drive I'm in this condition. I have attempted to reset the ecm by disconnecting my battery cables and turning the key (this worked, I've had the issue for a few months now and it only used to happen every so often, more so after a raining) but that doesn't work anymore. Scanned the codes found a p0606 and a p0602 code. Attempted to clear the code, nil. Nothing. When the problem was very intermittent, the truck drove fine when this didn't happen, but now (tried for over a week to clear this issue including a new map sensor) I cannot get the truck to properly start. I have heard that these trucks do funny things when the alt. Is starting to die, so I will be replacing it with a friend's to see if that fixes the problem. Really hoping that p0606 code is just make believe because 700-1300 for a new ecm is out of the question. I have attempted to start it with the ts mvp disconnected and it doesn't help. Prior to starting the truck takes around 3-5 seconds of cranking. When she is running healthy it only takes 1 second max.
