If your vehicle does not start, YOU DON'T NECESSARILY NEED A STARTER! However, did nothing happen when you turned the key (or pressed the button) to start your vehicle? Did it just "CLICK" when you turned the key? Did you try a jumpstart but were you will still greeted by a mocking silence. Then you could have starter problems.
A starter, sometimes properly called a starting motor, is just a big electric motor that spins the gasoline or diesel engine until it can catch and run on it's own. If you turn the key and the engine makes the normal rhaa-rhaa-rhaa-rhaa-rhaa sound that it normally makes but the engine just did not catch, then the starter and battery are ok. You need help.
