Thanks for the summary. Some initial observations/comments:
3) I've seen a BPC valve coil fail both open (high resistance) and short (near 0 ohms).
4) If you aren't getting 12V at pin 2 to the BPC (with connector disconnected), that would mean a blown fuse or bad wiring (not an ECU problem).
Checking for a short circuit would be low resistance, not infinite.
5) I don't believe that TCS cars have separate cruise control modules, so that should rule out that possibility on '92-'93 cars.
Have you solved your recent base boost problem? Replaced ECU? I'm curious because you were reporting the exact same issue I have been chasing. See message I posted on your previous base boost post.
