96 ZJ keeps Killing Computer???
I have a 96 grand Cherokee with the 4.0.
I bought it not running and am having trouble with the computer. I put a new computer in and will run at an IDLE but when I put it in gear and drive it a few feet it will just die. I lose all gauges and nothing works until I replace the computer again. All it will do it crank and crank. I took the computer out of my XJ and it did the same thing. It kills the computer, tried putting the computer back in the XJ and I get nothing, no gauges and just cranks and cranks. Not sure if its transmission related but the guy I bought it from had just replaced the transmission and it wouldn't run after that. Are they any tranny wires that could be crossed or screwed up that would keep frying a ECM like that?
