so im on my way to work today and i stopped to get a bite to eat. I get back to my car and it wont start. So i get help from a guy from work and he tries to jump start my car so i hear the starter trying to turn over and still no luck. Now im thinking the battery is dead and i need a new battery. So now im waitin for my friend to come pick me up to get a new battery and i figured what the hell so i get back in the car and try to start it and it starts the first turn. Does anyone know what might be causing this?
