Crank, no start, no fuel pressure

I am at a loss. We assumed with no fuel pressure and cranking but no start. After checking the fuse and relay for fuel and everything checks out fine. The wires look good, new fuel pump. Attempted the relearn procedure, new battery still no start or pressure. I swapped the A/C relay with the fuel relay and got the gauge to register one time but after that still no start. Checked all fuses in and out of car as well as relays. 

The car sat for six months without a battery before I got it, but had all the fuel problems before that. Scanner says no communication ensure key is on.

Unplugged the throttle body sensor the car now fires up but the Roma won't pass 1500. I cleaned the throttle body butterfly but it didn't change anything. I also jumped 87 &30 pin of the fuel pump relay but that made no difference.

Does anyone have any ideas? Thank you!
