A noid light would help you figure out whether the injectors are actually getting a pulse from the computer.
The other thing I've done on RBs and L series motors is to spin the CAS by hand and see if the injectors are clicking, probably best to do this with the fuel pump disabled.

Those early style fuel injectors+connectors always cause striff. 1994+ Series 2 pintleless injectors can be swapped in with a fairly cheap adapting kit should you want to replace/upgrade them. ie something like this:

By the way thats an awesome site zilver, are they who you import parts from?? could realy be interested in
the jecs 550cc injector package for 90-94 engines, and also those 350lph intank fuel pumps. would be more then
enough fuel for what i want to achieve.

Yeah, I import fairly regulary from them. Coz the owner of Concept Z Performance often offers a bulk buy discount. Additionally the combined shipment makes it further economical for everyone. I'll be liky doing a purchase for myself soon, and offering free or discounted piggyback shipping to club mates (plus the discount if applicable/Coz confirms).
I also have a selection of new OEM service parts for the Z32 which I resale at (+5% from what I sourced from Coz) if people need urgent supply of filters/timing components/etc.
The stock fuel pump is good for about 500hp - think it was tested by Specialty in the Z to struggle near 600HP. Dual stock fuel pumps is a common setup for High HP cars.
