Bad battery connection or pcm?
One day I went to start and it wouldn't stay for more
than 3 seconds, then it wouldn't crank, and the
gauges all starting twitching, and then it started
right up just fine, this keeps happening
intermittently. I want to say it's just a connection
issue but I'm not for sure. It has the 4.0
Check every ground cable you can locate making sure their all secure.... Then scan the vehicle for DTC's that will be stored in the PCM / Computor
If it any help it will unlock and lock just fine and when It acts up everything resets like the radio, average fuel economy, trip ometer, etc.
