So i am now still wondering why the Durango will crank, but not start with my original PCM installed. "Check Gauges" indicator is lit and no reading from the volt meter. I will start the search process over again. But to me, it still points to the PCM having caused an issue that will not go away on its own.
Open the air cleaner box, remove air filter, have someone turn engine over while you spray a little starting fluid in the intake, ( gas in an oil can or spray bottle is better, but starting fluid works), if it fires start checking fuel pump system....

thanks. kind of figured i'd have to start from square one and check for air, fuel and spark. and, is it only me.....or does anybody else think it odd that a PCM would get sand blasted?

No it's not odd, that's how they clean them, but if you get some dumb kid doing it while staring at the clock waiting for break, he could blow glass bead or whatever they are using in to case, it is only a tin cover after all.
