OK, here is the update. The car starts!
While researching the "CPS/crank position troubleshooting"... I came across this gentleman, Brian Minson.
https://youtu.be/ZSmehtE8Ctk
At 14:00 mark, he explains how to check the CPS.
It is just what YOU asked me earlier, "does the tach move?" I say no, but the amount of 'movement' is way smaller than I was expecting. I will look for this tiny tach movement, or not, the next time when the car won't start. In fact, it was to confirm this tiny tach movement when the car magically started. Brian's description of CPS failed car is 95% dead on with my experience.
Questions:
- is failing CPS sensitive to temperature? Ambient temperature? Or, engine temperature?
- Could a bad CPS stop the engine while driving?
As always, thank you for your help.
