When the starter refuses to crank, have you tried cranking in neutral? If you have voltage at two of the relay terminals, key in crank position, check the ground for the coil side of relay, 85, according to my info. The computer grounds that circuit. If there is no ground there are other issues that could cause that besides the pcm.
I have no idea why the seatbelt switch is involved. I even thought about unplugging that switch or bypassing.
If you could check for P and U codes. It might point you in the right direction?
