You MAY want to check your cigar lighter fuse. Unless I'm not remembering correctly, this fuse supplies power to the OBDII port, as well as the cigar lighter.

And, DO NOT flash the PCM back to stock - that just about guarantees an emissions check failure.

Edit: I just read your post more carefully, Norm! Sorry for duplicating you. Perhaps the fuse failed after the truck was returned to stock.
