Need a computer from a 94 2.5l m5 yj
My 94 yj's computer went bad. It has to be from 94 2.5 m5 yj. The years before 94 didn't have a stand alone computer. Thanks

My problem started when we did a engine swap. New engine wouldn't start(Turned over no fire, had fuel pressure). We discovered the black with blue stripe ground wire connected to the tps had no ground. Looked up the wireing diagram on aldata and found out that that wire is connected to K5 splice which is connected to pretty much all the sensors. The k5 splice gets its ground from the computer and no where else. I unwrapped pretty much the whole Harness from back of tranny up to the computer and couldn't find anything. We ended up jumping a wire from k5 to the firewall and it started. Ran pretty good but not perfect. With new computer i disconnected jumper and then tried to start and it works and runs perfect now:)

I have no spark and no fuel. I'm going to putting in a gm 5.3 or a hemi soon. Not sure I even wanna get the replacement puter, but would like to move it if need be. It is sitting in garage with no wheels waiting to get 33s and a lift. Then motor project begins. Gotta get my buddies over here to help with the zone lift that is sitting on work bench.

My Jeep goes 65 over the pass here going out of town now. It would do 55 before. Pretty gut less top end. I'm going to change gears next but i have to save up some. Next Jeep i get or build will have a 302 or 350.
