Mark - here is a picture of the automatic pulse module that you were looking for. It's out of my SRT with notes of how I think it should respond under certain conditions. I am having the "No Crank" condition. After the condition started, I had the RCM rebuilt by DJ and put a new battery in on 8/16/2019 (mine tested bad under heavy load). Still not getting any cranking. I am looking at your theory that the PTCM will give the "go" or "no go" to the PM to get the car started. I haven't dug into the PTCM yet but I did make sure I was getting voltage to certain pins on it and contiuity between it and the PM on common wires. As far as I can tell, everything is getting voltage and ohming out like it should if I am reading the 8W-30-5 diagram correctly. With all that being correct, I am not getting 12VDC at F1 of the PM when the key is turned to start like I would expect. So, I took the PM without the case on it and hooked it back up to see if I could get the starter to turn by manually closing the relay and that works - the starter will crank ... but the car will not start. Everything is hooked up as it should be, key gets turned to the "START" and then released to the "RUN" position and I can close the relay but all it does is crank - doesn't even try to start. So, now I am wondering if the PTCM isn't giving the fuel/ignition commands for the car to run and that might be why I am not getting any voltage at F1? The PTCM isn't giving the command for that relay to close? That "SENSOR GROUND" at A2 of the PM and C4/35 of the PTCM has me baffled. I don't know what I am supposed to be checking at those two points but I did confirm the wire between them is good.
