2014 F250 Says starting system fault replaced battery replaced starter checked all fuses and relays and electrical connections I saw posted on here years back. The question is no crank no start but if I use a jumper to cut out the starter relay it’ll crank no start and say starter system fault. The key fell apart and truck hasn’t started since. Saw on YouTube about possibly the key not being able to communicate causing the bcm to not talk to the pcm is there a way to bypass that or what else should I be trying

 

I don't think you are going to get much help on the electrical questions in this section of the forum.

Maybe try the main Super Duty section for your year?
