1992 GMC Sierra 6 cyl Four Wheel Drive 225000 miles

I have replaced the fuel pump, tank, filter, complete tune up fuel pump relay, throttle body and injectors, new distributer cap pick up coil ignition control module plugs gapped properly wires, I'm at a loss, I get plenty of pressure to the throttle body but dont get fuel from the injectors, am I missing something?
