Also with the windows not working can you talk to the drivers door module and seat modules with the snap on scanner? Cause now that I think about your truck has 2 data busses I'm wondering if something is killing your serial data line but the CAN buss is still working fine. Definatly going to need to get your hands on a accurate and complete wiring schematic for your truck.

When you replaced the BCM you did do the pass key relearn?

if it was security it would start and shut down. i have a diagram but no way to post it right now, did you test bcm connector c1 pin 2 pink wire for signal when in start position. the bcm sends "ign key resistor signal" on a white wire to ign switch and comes back on that pink. rest is serial data to ecm. ecm pin is c1-52 yellow/black to relay 86, appears to be a positive signal, test for 12v on 86 and ground on 85. rest is fine because you say if you jump it the starter works
