When you swapped engines from the 93 Cherokee to your YJ, did you notice if there's a CKP sensor on the bell housing? and does your YJ have it?, if there is , did you swap the PCM and the flexplate from the Cherokee to your YJ?.
We used every thing from the cherokee. We found two cut ground wires that went back into the wire loom, we hooked them back up and all is good at this time. Thanks a lot for your reply.
