Starting issues

Bad battery and DEAD battery are two different things. Have you charged it? Determine if the car's system has a parasitic draw

Unhook the ground cable and wire a test lamp in series with the ground. Look at the bulb in subdued lighting. ANY glow from the bulb (make sure everything is turned off) means you have a drain.

Might pay to charge it and take it to someone who can load test the battery.
I have charged the battery a couple of times. I even unhooked the battery cables and charged the battery by itself. I think I may have determined a draw. My son put a new steering wheel on and it kept triggering the horn. So we unhooked the horn(just the wire at the horn), but did not disable the horn switch. I think the draw might be that the horn is constantly being activated. We pulled the steering wheel off tried charging the battery again... nothing.. I will have to check to see if there is another draw, but its suspicious because the old battery and now the new battery didn't die until we put the new steering wheel on.
