1983 280zx won't start

I've been doing some much needed weight reduction/rust finding in my 280zx and now all of my interior lights will come on but when I turn the key I got nothing Please Help!!!!!:crying:

Let me try and narrow down possibilities the car ran before I started taking things out dash is still in and hasn't been messed with a ground wire had to be relocated when I took the radio out but that's it and now the dash won't turn on and the ignition won't either
