The car ran perfectly fine before it sat there. I bought another 300D that was in better condition. The terminals dont have an corrosion. None of the lights work headlights, interior, dash or brake lights (radio was stolen) I'll check all the wires and make sure they're tight and try starting it through the starter connetion on my next day off. ohh and no I didnt put the battery in backwards. Thanks for all the input.
