Ok so I figured out why it was grounding. I had that black wire with the ring connector connected to the starter positive bolt. I removed it and I no longer ground the starter, but I have no idea where it goes. I also don't know where that yellow/red wire goes. Any help would be appreciated.

 

Now the new issue is that I don't think I'm getting any power to the ecu. The green LED doesn't light up when on the on position. I can hear the fuel pump relay clicking when turning the ignition switch to the on position. The starter also doesn't want to fully crank the engine. I can hear it engaging and trying to turn the flywheel but that's it. I will try to have the starter tested at the local parts shop tomorrow.

Check your battery.

The battery has 12.6 volts. I actually got it to crank. There's just no spark or fuel. Fuel pump relay doesn't click when turned to the on position and I don't hear the fuel pump priming. I still get that rapid clicking from that black relay near the steering column, which I don't know what it's for.

Download a copy of the Factory Service Manual (FSM) for a 280ZX and you will know why the fuel pump isn't running. You will also learn where all the wires go.

Thanks, I've done quite a bit of searching and looking through the xenon website but they don't have everything in there. I think I'm just going to rewrite everything back to the way it was(stock) and see how it works because I've been getting positive outcomes pouting wires back to where they originally were before I followed the swap guide.

You need the Factory Service Manuals and wiring diagrams for both of your cars - 280Z and 1982-1983 280ZX. Then make sure you understand that turbo swap wiring diagram.

Thanks for the link! I have the 280z paperback manual but it's all torn so this helps a lot. I will do some research and reading
