Hey all, I recently bought a 1980 280zx factory manual L20. When I bought it the engine and transmission had been removed, I have fitted it back in and wired it as best I can figure out however when I connect a battery and turn the key I can't even get the starter to turn over. So I'm asking if anyone knows if there's any little secrets to these cars that will make them not turn over?

Improperly wired starting circuit, bad ignition switch, poor battery condition, corrosion in/on wires. Lots of things to consider.
