Hello and welcome to JustAnswer!
If it's actively setting a code for the cam and crank sensor and they've been replaced with Mopar parts then you have an issue with the sensor ground or reference voltage to both sensors. The cam and crank sensors share a sensor ground and 5v reference, if one of the circuits is open or shorted then it will prevent the sensors from producing a signal.
The problem could be wiring, the PCM, but it may also be in the TCM since the TCM gets a direct crank sensor input. With the TCM unplugged does anything change?
