My 96 cherokee won't start it quite on me yesterday at a stop light just turned off as if I had turned the key off and wouldent start again. The engine is getting fuel so it's not pump. Ran diagnostics computer on it came back with a code saying that sometning wasn't getting power going to the pcm. We think we have it narrowed down to it needing a new pcm has anyone else had this problem?

 

Post the code, always helps to share the data. Have you checked to see if you are getting spark?

 

You can have fuel at the rail but not enough pressure.......
