This finally wraps it all up.
I received the P06-A52 ECM I bought on Ebay from a wrecking yard in St. Louis.
Then I spent hours checking the wiring for shorts, continuity, voltage. I couldn't find anything wrong. I did learn that the wiring diagrams for the connectors are a little confusing: I thought the views were from the front of the connectors (looking in to the holes), whereas they are from the rear, where the wires are, looking towards where it would plug in to the ECM --(Duh !). Makes a slight difference.
So, finally, I gave up. I did all of these checks because I was afraid the new ECM would instantly burn out too.
I plugged in the new (used) ECM. The car started in one-half second and works perfectly.
Case closed. Once again, thanks for all your advice.
