Techsoft list some wires for door trigger that need to be diode isolated. I can find all three wires in the Pink BCM bolted above the fuse box, but they don't trigger any doors!!!??? anybody ran into this?

are you sure you use the "negitive" trigger. Also may have the diode back wards.

I doubt that "all" the diodes are bad, but stranger things has happen, but check the diodes see what they read.
Maybe a bad alarm brain, try and use a trunk/hood trigger to make that it works.

If there is a light around the keyring you will be able to catch all the doors off of that wire.
