I HAVE A 2004 JEEP GRAND CHEROKEE 4.0. I HAVE REPLACED THE IGNITION COIL, FUEL FILTER, AND PLUGS. I AM GETTING FUEL AT THE FUEL RAIL. IT STILL JUST TURNS OVER AND OVER AS IF THERE IS NO FIRE. WHAT NEXT PLEASE?

The ignition system is controlled by the powertrain control module (PCM).
The ignition system consists of: Spark Plugs
Ignition Coil(s)
Powertrain Control Module (PCM)
Crankshaft Position Sensor
Camshaft Position Sensor
The MAP, TPS, IAC and ECT also have an effect on the control of the ignition system.

If it is confirmed that there are no sparks, then you need to go down the list and check those.

Was anything done prior to this occurring and have you tried to retrieve for trouble codes?
