Hi all, I have a dear friend that is in trouble with his dodge viper 1st gen. The 2nd and 3rd cilynder don't fire, there is no spark. The coils pack is OK (it's new) and also the wiring seems ok but i'm not so sure. We think that one of the 2 ECUs is broken: 4709384 (Engine Powertrain Controller Module) 4708229 (Ignition Control Module) I have cleaned every connector to be sure that every signal is OK. In Italy is not a common car, so is very difficult (if not impossible) to find a garage that could handle this problem. Someone of you have experience or a wiring diagram of this car? Thank you!
