The other thing you could try is to remove the return line from the reg and turn on the ignition. If there is not enough pressure to bypass the reg, then you will never start it.
Then check spark. I can test your coil packs, PTU and injectors with an ignition tester I have but you should make sure you are getting power to everything first. Chuck a noid light on the injectors and see if they pulse. The Z32 AFM won't work on the standard ECU as it has a different resolution, but I'm not 100% on whether it will stop it from running completely. If you get stuck......I'll happily buy the car from you for $1
