Leeroy Posted December 11, 2016 Author Share Posted December 11, 2016 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.

Leeroy Posted December 11, 2016 Author Share Posted December 11, 2016 Also, this relay is constantly clicking when I attach the battery cable. I'll have to do some more research on what it is and what it's for. Quote Link to comment Share on other sites More sharing options...

Leeroy Posted December 12, 2016 Author Share Posted December 12, 2016 Don't know if this helps 20161212_105055.jpg It does thanks, but I don't know why I have 3 wires coming out. I thought that black wire with the ring connector goes there too but it grounds my starter. Quote Link to comment Share on other sites More sharing options...
Leeroy Posted December 12, 2016 Author Share Posted December 12, 2016 Here's the two wiresIMG_0974.JPG Thanks for the photo helps a lot. Now I still don't know where that other one goes. Quote Link to comment Share on other sites More sharing options...
Leeroy Posted December 12, 2016 Author Share Posted December 12, 2016 [quote name="Miles" 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. Quote Link to comment Share on other sites More sharing options...

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.

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.

skirkland1980 Posted December 20, 2016 Share Posted December 20, 2016 If the block has 12 volts the block is not grounded. Quote Link to comment Share on other sites More sharing options...
