first things first... you need a good charged up battery to operate a car... and to keep it good and charged you need an alternator that will supply the juice to the battery....
no one here can tell you what one it is.. if you keep on getting jumps and the battery is pulled down too much then yuo gonna get another battery and put it in and it will start right up... but if its the alternator then when that battery goes down like 10 minutes of driving then you gonna not have any power left in the battery(eventhough it was new).....
