Why won't my car start?

What happens when you turn the key tells you the system. Nothing at all — dead battery or bad connection. Rapid clicking — battery is too weak to spin the starter. One loud clunk and silence — bad starter solenoid. Engine cranks but won't fire — fuel, spark, or anti-theft system. Each of these is a different fix, so don't replace parts until you've narrowed it down.
