If you dont' have a fuse blown like the two under hood or the one under the dash, specifically fuse 12 23 or 29 then i'd say if the relay is transfering power then i'd have to say its a security problem. Youi could always try to ump the relay to see if it cranks.

I am not getting a ground signal out of my PCM to crank the engine even if I jump a ground to the relay it will not start no injector pulse. It seems like a bad PCM but I installed another one but have no communication. All fuses good good powers and grounds, also load tested wires they are all holding battery voltage. I have disconnected every other module in the vehicle thinking maybe one was pulling the data line down but that was not the case

It has to be the security system then, not allowing it to start. Can you reseet the security system?I did find this on the ford tech service though it's a tsb.
