The injectors must have voltage at one of the wires when the ignition switch is turned ON. The pulsing is controlled directly by the PCM and if voltage is available and they do not pulse while cranking, you have a possible fault with the PCM.
Was any repairs done prior to this occurring?
Did you check the PCM harness for loose contacts?
