I hope you didn't throw out the donor turbo car. I did the swap a long time ago and before I did I checked the wiring in the manual and they are many differences between the 2 models. So I took the easy way out and that is to swap in the entire wiring harness from the turbo car. This will save you a lot of guess work. After cutting and splicing you ended up screwing up the wiring harness.
The turbo car has a fuel pump modulator sitting under the dash and on top of the ECU area. You need this modulator to prime the fuel pump. There is another 5 or 6 wires connector near the ECU that you need to splice in the power. If you have no spark then one of the wire in this connector is not getting the power. Double check on it. It's been a very long time ago since I messed around with the Z cars. I still have several in my garage here including a turbo ZX. So if you still need some help I can check and help you out. Send me a PM with ur number and we can get in touch. GL
