After much aggravation, the compressor has been replaced.
It's very difficult to finagle it and it's bracket to leave enough space for the compressor to clear. Another pair of hands would've been helpful.
I got it all together, new little pulleys, all looks good!
Got the fan shroud and fan back in place (I'm getting good at doing this without disturbing the cooling system) and had every detail and bolt back in place.
NO START CONDITION! No spark!
10PM, I packed it in for the night and had a beer, I deserved it.
A crank but no spark condition on an LS engine is usually the crank sensor. I confirmed this by setting a code, cranking for 8 seconds or more twice.
The crank sensor is COVERED BY THE STARTER.
After removing the chassis sections to get to the starter and shoving it to the side, I unplugged the crank sensor. All looked good.
I discovered the crank sensor wires, starter wires and AC compressor wires are in one harness that passes under the engine. I need to get the wire off the starter to let the entire harness hang down to fully examine what's happened.
Of course it starts raining and I have a family thing tomorrow so my daily driver work vehicle won't be touched by me until Tuesday.
If only that damn pulley came off the compressor....
