To jump start, You need someone to help you

Basically you need a jump start cable to connect the batter from another car to start your car. Most Americans would know this. Before you do that, check your battery connectors (+ and - ) make sure they are tight and clean -not covered with white powder.
When you turn your key, does the starter turn? Does the engine turn? Do you hear tatatata. Can you turn your head lights on? If not, your battery is dead, or bad connection. If your start turns strong, and the engine turns, but just not start, then, you may have other problems... You have to start from your battery.
