Please review your initial test results: Did test 2A and 2C have the MAP Sensor electrical connector disconnected? Do you remember? Side Note - test 2B was skipped or deleted, is not in spreadsheet.

Yes tests 2A and 2C did have the MAP sensor electrical connector disconnected.

Test 2B was skipped because engine running or off with key on made no difference between tests 1A and 1B.

In other news: I thought the 0.7v Vref was low and should be 5 volts from online things I read so I replaced the PCM with a good used one I had but did not get it programmed at the dealer to run the car figuring it might still power the IMRC Module circuit and it did but I still measure only 0.7v to the #2 module terminal. This would seem to rule out the PCM as being bad??
