So awhile back I tried to jump start my 1982 280zx turbo. Foolishly I swapped the posts on the battery popping a fusible link which I replaced. I have also replace spark plugs, spark plug wires, distributor cap, rotor, and ignition coil. But I am still left with no spark. I feel like a huge doofus because if I had swapped the posts the car would be fine. Also I did get a new battery but it has lost charge because it has been sitting but I can jump start it without a problem using the correct posts this time to try and start the car but I am still left with no spark. I do know that a possible problem is the ECU. is there a way to test that and anything else going forward? Because all other possible solutions going forward I know can get costly quick. So I am trying to avoid buying unnecessary parts. Any help will be greatly appreciated.
