I have a 2000 Challenger 2000 with a 240hp Mercruiser M2 efi engine. I’ve had it since it was new (only owner). I had troubles a few years back that I was able to figure out and replaced a sensor. No trouble since then until this past Sunday. Started fine and took off like normal, went about 1/2 mile and just shut itself off. Tried restarting and it wouldn’t restart. Waited 5 minutes, and it restarted. Idled back to the launch. Replaced the battery (7 years old) Replaced the plugs, Used my computer with Diacon Rinda efi diagonostic software and it showed all sensors tested good. I used a multimeter to check resistance of stator and trigger - both tested correct for ohms value per service manual. Replaced the ignition control module with a good spare that I had from last problem years ago. Pulled new plug out of two spots and they have a brown residue with a small amount of fuel/oil on them.
I haven’t checked the cdms or injectors them selves due to the difficulty to get to them.
Adjusted the TCM to 0.3v and checked it went up and down in value as I rotated it.
Worried that it might be the ECM. PN is 824003T31 supersedes 824003A0
Have had no luck finding a new or even used one. Anyone got a line on one? Or a clue as to why it turns over but won’t start.
Baffled and frustrated with this situation.
