A few years ago I had a problem with my 94 xj not starting in weather under 35 degrees. So I replaced all kinds os sensors and cap rotor plugs and wires. Nothing worked. So finally I took out the computer and heated it up with a torch and hooked it back up. And what do you know. IT STARTED RIGHT UP. imagine that. So with that problem fixed I went to a junk yard and picked up a new computer for bout 75 bucks. So when I had the same problem in my 91 xj that I just bought and it didn't even start in warm weather I took the computer out and put a new one in and there you go. It started right up.

 

Wow, never heard of a prissy ecm. Learn something everyday. Glad it worked out for you.

I'm glad it worked out to cuz I was about ready to scrap it for some money to get another xj
