Can you verify that you are getting fuel pressure in the injector rail? If not, verify the ASD relay is good.
Assuming you have fuel pressure, then one would have to suspect the either or both the crank or cam position sensors. The crank position sensor should center up on the mounting bolts and pretty much align itself, but not always. If you have used aftermarket non-Mopar parts, that can be an issue, but even genuine parts can be an issue. Loosen the two bolts and push the sensor towards the flywheel with as much hand pressure as you can while you evenly tighten the bolts.
Still nothing? Okay, here's a real weird one to try. Make a jumper wire about 4" or so long. You're going to jumper the ground terminals of the fuel pump relay and the ignition relay. The PCM provides ground to the various relays, they already have positive power from the Power Distribution Center so if the crank and cam sensors are good, and the ASD relay is good, it should fire off. After a few days you can pull the jumper and everything should be back to normal.
