    first off, welcome to jeepz!!! i have an 89 and the biggest problem i had w/not starting was the ECM (electronic control module) - the little "black (actually silver) box" that lives in the engine bay that controls everything (mine is under the radiator recovery bottle on the driver side - great place for an electronic device... nice and cool - catch the sarcasm there?!?!?!) - test it per your manual or you can check your coil, battery connections, all the basics - but its prob. the ecm that fell victim to the gremlins... g'luck and let us know how it turns out... we can usually help here - and welcome again....

    thanks for the advise ........and thanks for the welcome ........anyways my jeep is a 4 cylinder where else can i find that part is it in the engine bay or in the jeep ....i checked under the coolant reservoir and under the battery and i cant seem to find it....would it be posible that it might be in the jeep???

    Check on the firewall below your brake master cylinder area. Mine's a black plastic gell encased ECM. Your's being an 89 might be different looking, but thats where mine is located. Stupid question, but you battery does have charge right?
