Is the PCM actually firing the coils? Injectors? If you got a cam sensor code, failed sensor would prevent the engine from running.

Need to address the cam sensor code. Your engine is sequential port fuel injection, PCM needs input from the cam sensor to know which injector to fire. If it doesn't have that info, it doesn't fire any of them.

For the truly important sensors, you are much better of staying with genuine mopar parts. A fair few of the aftermarket fellers simply don't work as well, and you end up with mystery misfires/codes. Cam and crank sensors are right at the top of that list. You don't necessarily need to buy them from the dealer, you can find them cheaper from various sources online.

I have found that dodge has a radically different definition of 'normally' than most any other manufacturer.....

Look it up on some mopar website, doesn't matter which one, I think they all hit the same database anyway. Get the mopar part number, and then do a google search on the number, should turn up quite a few results, and if it is GENUINE Mopar, it'll work. (new please, not used.)
