rain= no start
i have a 89' MJ with a 4.0. Today i got in it and it started right up and i went to my friiends house to work on his Toy. 5 hours later and some rain also, i go out to leave and it doesnt start. Turns over and the batt. volt is fine. It also is gietting fuel. no idea whats up. So we ended up bump starting it then the idle went crazy it was around 2500 and 3000!! i dont know what it is up. It happed in San Fran one a rainy night at SFFD Station 7. Same deal but i had to get it towed back to my house and once it got of the truck it started right up... any ideas??
