Not much to add, but I had somewhat similar problems a couple years ago. I was getting a CPS code after a no-start problem, replaced it, and still had the code and no start. Fuel was good, no spark. Switched out the disty, no change. Replaced the ECU, and the car started, CPS code was gone, but then got new codes for FPRS and temp sensor. Then I put the old ECU back in and it still started!
Next day it wouldn't start, and the CPS code was back. Put the new ECU back in and it started, CPS code gone, FPRS and temp codes back. Replaced FPRS and temp sensor, and cleared those codes. I also tried to clean as many grounds as I could. The car has been starting fine since then ( it's a stock race car so I only run it a dozen times a year ), but I never really solved the problem and fear it may come back at any time.
These cars can be finicky. Good luck with your issue.
