Ford F150 Won't Start

Automatic? Manual? Can it start in neutral? How about the starter relay? Test it or swap it out? Regarding the tranny type, check the following link about the DTR and it's input to the starter relay: https://www.f150online.com/forums/electrical-systems/423285-2000-f150-will-not-start-ignition-wire-problem.html

I try changing the module

Make sure the engine isn't locked up. Easiest way to do that is use a socket wrench and turn the bolt in the front end of the crankshaft. Only turn it in a clockwise direction and do not have the ignition switch turned on when you do this.

Battery tested? Did you replace it?

starter relay?? did not know that there is one that exists. hmm, good to know. I just replaced my duralast battery of 4 years ( it started struggling to start for 3 days). The battery tech who replaced the battery and core, told me that the starter has nothing to do with the struggling of the motor to start. Sounds awkward to me. Maybe I overlooked the starter relay((
