Subject: RE: 81-83 EFI system circuit analysis: Was (RE: IML:
Question, of course!) It would sure be interesting to have a test light monitoring the output from the ASDM when this happens. If it dies with this line high, the problem is elsewhere, but it sure sounds like the ASDM is shutting it down.
The cause could be any one of the shutdown causes, or noise.
However, the fact that it won?t restart until it cools off sounds like the distributor pickup coil ?open? that was somewhat common with these ? that would of course be heat sensitive, and would cause a loss of ignition pulses, thus the ASDM would shut it down as it is supposed to. Have you replaced the reluctor and magnet? These are cheap, and relatively easy to change ? I?d say it?s worth a shot! The EFI cars have only one set, not the two that are used in normal Mopars. You will find it easier to pull the distributor to do this, and you do need to reset the initial timing afterwards.

Thanks for the clarification, Dick. Agree the ASDM design looks like an afterthought. Reminds me of some of the quick fixes they made us do to ship "prototypes" out to customers. But my quest here is not purely academic, I have this machine running near perfectly, however, out of the clear blue it will suddenly just die. Does not stumble, cough, or anything, just dies at random times. All modules are the late production, non-meltdown, all new filters, cleaned tank and pickup filter. Will not restart until it gets stone cold again. Has fuel, spark, and turns over, but no start. Same effect with bypassed ASDM. That's how I isolated the common lead to the CCC. I am about to bite the bullet and gamble on a "new" or "refurbished" CCC. Even after 6 months on this project I refuse to trash the EFI.
