I have a 98 Cherokee with a 4.0L and an auto trans. I have had issues with the PCM and TCM not communicating for a while now which was causing a check engine light and a P1698 code. I was also experiencing intermittent issues with my fuel gauge not reading and my volt gauge showing 19 volts. Once in a while my check engine light would shut off and my engine would die. It finally died the other day and would not restart. I noticed it will not do the self diagnostic check on the initial key up and the check engine light will not come on at all. I did get the check engine light to come on once and it started and ran. As soon as the check engine light turned off it died again. The only common link I can think of is the PCM/ECM. Any body have any ideas or know a diagnostic test I can run without a scan tool to verify it is the PCM. I have a factory service manual but I will not have access to it for about a month because it is at my parents house. Thank you for any advise.
