I have heard not to run a Cps other then jeep so I purchased a factory CPS from jeep and low and behold it would not start after I went to leave after driving out for lunch.
I was curious why heat causes these to fail and can they be insulated?? Is there another brand to try?
Any help would be appreciated
Are you running a header? They generate more heat. Wrap the CKP wiring in several layers of aluminum tin foil and see if that helps.
