Why does my car only turn on when I jump start it?
If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can’t hold a charge when the alternator is shut off.
Why do I have to jump my car every time I turn it off?
The most common reason a car might need to be jump started is a weak or dead car battery. This is what most drivers run into, especially in cold weather. Other problems that could require a jump start are malfunctions in the starter or alternator, dirty spark plugs, and clogged fuel lines.

Why won’t my Car take a charge from the alternator while driving?
It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery.

Why does my starter motor not start my car?
If the starter motor doesn’t crank and the lights are dim or don’t come on at all, the battery is dead or close to it. The cause can be as simple as leaving an interior light on overnight. A jump start should revive the battery, but keep jumper cables handy for the next time you try to start the car, just in case the problem lies elsewhere.
