Chances are you have the coil packs and/or injector connectors on the wrong side. Also check the CAS, make sure its plugged in all the way. Go under "Everything you need to know about the z32" It will have a factory service manual, that should help you out.

Are you absolutely sure you do not have the fuel lines swapped? Here is a diagram how they go.

Last, but not least, have you checked the ECU for codes?
