If your car won't start, the first thing you should check is the starter. If it's not working, you may be able to replace it yourself. The starter is a small motor that turns the engine over, so it can start.
To replace the starter, you'll need to remove the battery and disconnect the wires from the starter. Then, unbolt the starter from the engine and remove it. To install the new starter, reverse these steps.
Before you begin, make sure you have all of the tools and parts you'll need. You'll also want to consult your car's owner's manual for specific instructions on how to replace your particular model's starter.
