I am working on a 1994 gmc suburban with a throttle body injection system. I am not getting fuel out of the injector?

Tried fuel pump, fuel filter, both injectors, confirmed power to injectors.

check the pick up coil in the distributor. it should ohm out at 800-1600 ohms. there should be ac voltage cranking. the computer sees this signal to fire the injectors below 200 rpm.

I do have resistance on the pick up coil. I do have ignition spark. The truck will run if fuel is "hand delivered" down the carburator. Anything else?
