I have a 2000 Ex with the 7.3L and a Ford Command Start ( not sure which one ) when I purchased the Ex the command start worked fine. Now the glow plugs will kick on and turn off then it will crank but won't fire. The Ex starts fine using the keys but won't fire with the command start. I am thinking a PATS issue but any other thoughts would be appreciated.

 

I'm thinking a PATS issue too. Not familiar with the Ford system, but most aftermarket ones you either need a certain module that is supposed to play nice with the PATS system, or more often to get a reliable start, you go with the box that you put the head of a chipped key in so the PATS is disabled.
