    I found the problem !! and fixed it.

    So after rechecking the relays, and the pressure sensor and finding nothing...
    I just wanted to re-verify the 12v at the trigger wire on the compressor (which
    I didn't get last time.
    -
    The 12v was there when the car was started and the A/C button ON, so
    I decided to go ahead and pop off the clutch from the compressor (if it would
    come off).
    -
    So, I took off the belt. Held the center firmly and removed the 5mm allen bolt that holds
    the face of the clutch onto the front of the compressor to have a peek and see if I could
    verify some part numbers.
    -
    As I took that face off the front, 5 washers fell out off the spline shaft. Upon closer inspection
    it was obvious that the face I just removed was a calculated distance from the surface behind
    it, and that normally the magnetic field jams those two surfaces together.
    -
    I decided to remove enough washers to allow the face to still spin freely and not bind against
    the pully wheel.
    -
    It worked! I started and stopped the car, and engaged and disengaged the A/C at least 20
    times and it fires right up each time. Cold as the winter in Siberia!
    -
    So, thanks to all that added thoughts and advice. Chalk this one up to the "who knew"
    category!
