My car hasn't been started in at least 6 months. Went and bought a battery for it and the car has power when I turn the key but does nothing when I try to crank it. As if there is no power to crank but everything else has power. I took the battery back and they said it was a perfect battery.

It started 6 months ago with no problems, does anyone know what it could be?

Could it be related to the clutch? because I need to bleed it as well since it's falling straight to the floor, i believe it has air in it. Which was supposed to be my project but now, the crank/power issue is really bumming me out.
