Thanks for the tip. It sounds like grounding issues might reduce the spark sent to the engine. I can work on that. Always interested in other possibilities though. It is still original Renix. (I am guessing that means pre 91 Chrysler HO). Not too many mods have been done to it. I was told it had an xj rear axle. I was assuming that was to help with the lift more than durability. It was repainted the stock gray, but it is pretty standard besides the lift and wheels. No aftermarket bumpers etc. As for the photo, I am working on getting a photo small enough to fit in the profile pic.

Today I bought an '88 long bed MJ. 4.0 5 speed. It is in pretty good condition (body and everything). It has a 4.5" lift on it and I thought I got a good deal on it. I knew coming into it that it will require a bit of maintenance ... I test drove it, it started right up (seller was putting new spark plugs in it when I drove up). Drove it around and it seemed like the engine ran smooth etc. It had 165k on the 4.0 which shouldn't be a problem at all. It was well cared for. I negotiated, bought it and had the title/bill of sale in hand when I went to drive it out of his driveway and it wouldn't start. We opened the hood and I put as much accelerator as I could into it to start it. He grabbed the throttle body and pushed it all the way down and ... vroom. It started. I have started it now multiple times this way. It also seems to have a low idle when it is started. Any idea what could be wrong. Someone suggested fuel pump ... but I would think that would be an all good or all bad situation. Anything else? -Happy to Join the MJ club!
