Thanks Jerry, I wasn't thinking about the grounds as so much of the ECU/PCM functions are working, but after your suggestion, I would imagine there are many circuits on the board getting there grounds from multiple points.
ECU/PCM plug 5 pins 5,6,7,and 8 are all grounds connected to G101. Measured resistance from plug C5 to G101 and all were good. (.2 ohm) then measured from ECU/PCM plug 5 direct to battery ground and all were good, same .2 ohm.
There are other pins on the ECU/PCM labeled as sensor ground (plug C3 and C4) but believe these are more descriptive, unlike the 4 pins on C5 which are shown as grounding points where expected results can be compared to measured results.
I tend to agree the ECU/PCM would rarely go defective, so I think I may be at a point where I need to drive over to the local Chrysler dealership (sorry Pizza guy) and talk to the service manager to see if he has a tech who was trained on these cars and if they still have a DRB3 scanner that they can connect and just tell me what the Reason for the "no start "condition is. Hopefully, it would point to why there is no heater operation on the o2 sensor as well.
I would expect the DRB 3 scanner to indicate a skreem fault or not. From what I have watched on skreem video's, it seems the skreem fault does not kill the fuel pump as the engine will start momentarily twice. Cycle battery power and the same results. Don't think that would happen without a fuel pump start and I don't have a fuel pump signal.
Just thinking out loud
