There may be a problem with the distributor reference pulses getting to the ECM so that it CAN fire the injectors.

Since the fuel pump operates, the ECM is obviously controlling the relay. Because the engien will eventually start and run, the ECM is obviously (electrically) capable of firing the injectors. The fact that it doesn't fire the injectors during cranking could be due to an ignition switch problem, distributor connection problem, or VATS problem.
