84 Westy 1.9L

She started this morning! So at this juncture, I'm not planning to crawl under and hook up the remote starter, test the NOID, etc.

Correct me if I'm wrong (I haven't revisited prior posts) but if the engine doesn't restart when it's warm/hot, could that indicate a bad Temp II sensor? Or does it indicate a different "bad something" perhaps?

Again, symptoms: 1. Replaced ECU, engine fired right up. 2. Drove 5 miles, shut her off, engine would not restart (last night). 3. This morning (engine cold), she fired right up (immediately on the first turn). I shut down and restarted several times just fine.

Any thoughts? Thank you.
