The signal that the computer uses to fire the injectors actually comes from the ignition module inside of the distributor.

Some applications also use the oil pressure sending unit to shut down the fuel pump and injectors if there is not enough oil pressure to run the engine safely.

There might also be a burnt fusible link at the starter that controls part of the power to the computer, you will know a burnt fusible link wire when you find one because it will stretch like a rubber band.

Be sure that all of the ground wires are tight, especially the computer ground wires at the back of the cylinder heads, and the computer ground wire that should be grounded next to the thermostat housing.
