96 Sierra 4.3 vortex pcm 16244210

Have spark and fuel, injectors are not fireing. Have 12Volts to injectors and computer. Control lines to injectors form pcm are not switching at the computer and computer has good ground. Is the pcm bad or something else telling the computer not to fire the injectors...? Thanks

ignition module is gone goofy. Not giving the ref. signal to the PCM to toggle the injectors.

Try that one and see where it takes you
