Big time Electrical Problems need HELP!

I bought a 1977 280Z as my first project car, from the local penny saver. After pushing it home, we stated the restoration. My buddy removed the starter to check it out, and replaced it with a NOS starter. When my friend was installing the new starter, he switched 2 of the wires (i dont know which) and when i turned the key to test it out, sparks flew...and nothing happened. All of the electrical would not turn on and turning the key did nothing. It has been over 5 months since this happened, and I have replaced, the ecu and fuel pump relay. All of the fuses are good, and the ignition switch is also good. I have no idea whats going on and dont know what to fix. Can anyone Help me

Did you check the fusible links. They're the wires in the small boxes on the passenger side fender. Check them with a VOM. Do a search and you'll find a wiring diagram for '77 280Z. It's a great diagram and will be lot's of help.

 

Hope that helps,

If the fusible links are ok, you should also check the ignition switch. The white plastic part on the back of the key switch, where the wires hook up. It can go bad or could get shorted out with what has happened concerning the starter. When they go bad you can remove them from the switch and use a screw driver to turn them further then the switch can and sometimes get them to work. I would think the fusible link would blow first. Thats what their there for, but they are slow burn fuses.

I would replace in order of less cost and work my way down the list.
