I replaced the engine on my friends 92 Cherokee (4.0) and now it will randomly set the check engine light while I try to start. I have replaced the coil, wires, plugs, and the N.S.S. on the tranny as they were bad anyways. Afterwards it would try to fire off but only turn over. I finally got it to sputter/die and now it won't give the light. How do I check the ECMs power?
