Have you tested the batteries? The PCM must see 10.5v while cranking for it to tell the injectors to fire. I always get motorcraft 850 CCA. I think I am going to need another set soon.

If it is not turning over at all it could be the starter solenoid. Have you checked to see if you are getting juice to the starter with the key on? Check all connections are good and clean and check fuses. Also, you can try to start it in neutral. There is a a relay for the starter.
