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.

Have you check for an ignition spark

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?
