It will crank but no start. We replaced camshaft sensor, crankshaft sensor, and ignition coil rail. Anyone have any ideas besides junking it.

Was the WJ running prior to problems?
Is there compression?
Any incidents occur that resulted in problem?
6L or V8?
You have treated the ignition system. Is there good spark?
Is fuel pump running and is there good fuel pressure?
Assume there is also air.
Fuel + Air + Spark = Fire
Does it try to start?, ex fire but not keep firing?
I would be suspect of Throttle Position Sensor, EGR valve stuck, Neutral Safety Switch.

Have you checked to confirm that you're getting good spark? Also check the IAC valve too. If it's dirty enough that could give you fits too.
