It sounds as if the antitheft system has shut down the fuel injectors. Check for injector pulses with a noid light.
Is there a theft or security light lit up on the dash? Does it come on steady or blink?
You state you have good fuel pressure, what was the gauge measurement?
You verified spark on all cylinders.
You state you checked injector pulse with a noid light. Did all injectors flash the noid light? I highly doubt that all of the injectors would become instantaneously plugged so try doing the noid light test again.
Also, you did not answer my question about the security/theft light.
