If you check the plugs in the dead cylinders do they show evidence of fuel? If you listen to the injectors using a stethoscope or screwdriver can you hear them tick? If the injectors are not firing but you are sure the wiring is good the next place to look would be the ECU. You could try switching the wiring from a good injector to a dead one and see if that brings the cylinder back (injection timing will be way off while doing this so just test it for a short time at idle). Good luck.
