5.3 swap ready to start.. no run.

This is the Email i sent Brendan at LT1swap.com around midnight last night. (he reprogrammed the PCM)
Maybe you guys can help, yesterday was miserable and this was the icing on the cake.

Having an issue with the 2001 5.3 swap. (into a 1972 C10)
Cranks wont run, no sputter or anything.
Also the OBD2 scanner port wont link to the PCM (green data wire, has cons12v and grounds)

Crank angle sensor is plugged up, pretty much left every sensor plugged in
Block is ground to the battery using the 5.3 batt cables neg, other is ground to the frame, rear block ground is attached to the firewall
Coils are getting 12v, just me, so i cant see if they're actually firing
Fuel pump kicks on to prime the system every key cycle, has pressure
I have 12v to the injectors. (The engine only sat 2mo)
All 4 fuses have power

Side notes,
My main trans connector is smashed from the wreck, but i drove the 01 truck into the shop.
o2's are not plugged up at all
Pins were removed per the site guidelines
F11 and E3 neutral safety switch signal are open and not attached to anything. ?

I triple checked all my connections before hitting the key. I was certain it would fire first shot. Nope..
I would think there's a power/ground issue with the PCM but the Fuel pump relay signal is working.
