You have a rather large misfire going on there, and from what you wrote I'd begin with your fuel injectors.
Your first steps would be to clear that area carefully, and remove the connectors one by one which can be a hassle, looking for corrosion and continuity. Most likely a good cleanup of the expected green crap will get you going, but inspect all wiring and connectors in tat area for the same corrosion and clean, clean, clean...IACV, PTU, CAS and CTS sensor connectors all suffer from corrosion so more work is beneficial.
Also, with the way you wrote your post I'd also ohm your injectors following the steps in the online service manual you can find in the "everything you need to know about the Z32" sticky on top of the Z32 page.
The OSM also has all of the other test procedures and some troubleshooting areas to help you diagnose and repair your problem if it's more than I covered above, or be able to point your mechanic to the right area if that is your course.
Good Luck!
