no spark
i have a 96 xj 4.0L that wont fire, it turns over but for some reason it wont get any spark. there is pressure in the fuel rail, the fuel pump turns on, the starter is turning over i replaced the coil wires and plugs, cap. heard this might be an ignition control moduel (icm) failure or possibly a crank positioning sensor (cps) failure ive ran through all of the usual suspects and wound up here begging my fellow jeepers to help a bro out thanks

Coil, I think it's cheaper. If it don't work, refund and get a cps... Check fuel pressure, should be something in the forties
