2.7t wont start after timing service

I have performed this service on two other cars without issue. Here is the short of it, I had installed a gates racing belt and could not stand the whine from it any longer, plus I had a boost leak with a torn throttle body boot. I ordered new 710’s valve cover gaskets and an aluminum thermostat housing. I replaced them all, in the mean time my battery died and I tried jumping the car off without any success. Installed a new battery and all seems fine other than no spark from either bank. 40 amp ECM fuse was blown and replaced still no spark. VCDS cannot communicate with ECM. Trans gives me p1850 missing message from ECU.

Any ideas? I hate having it towed to the yahoo’s around here…
