The only way that the faulty charger may have damaged the PCM is that the battery is being charged inside the vehicle, with the battery terminals still attached. That was not how you did it, right?
The only way I know to check the PCM is by using Chrysler DRB-II scan tool.
Before you replace the crank sensor, test it for voltage. Your Haynes manual should tell you under Chapetr 6: Emission.
You may also want to check the EGR valve. Not on a Chrysler, but I had a Nissan and a VW didn't start due to EGR valve.
