No crank

What is your question?

Truck is 02 F250 V10 4x4 SD. New parts: starter, neutral switch, ignition switch, pcm, starter relay & probably other stuff that escapes me at the moment. If I use a momentary switch with the key on it will crank but NO fire. I've cleaned plus installed new grounds to the frame, cab & engine. Now I'm thinking bcm - Ford tech suggestion. ?? Not a bad truck but I'm out of ideas & patience. Any ideas would be appreciated.

What makes this problem better or worse?

Always the same
