Why won't my car start?

A car that won't start is usually caused by a dead battery, faulty starter motor, or failed alternator. If you hear clicking, the battery is most likely dead. No sound at all often points to the starter. A multimeter test on the battery (should read 12.4-12.7V) helps identify the problem.

Why is my check engine light on?

Why is my car overheating?

How do I know if my battery is bad?
