When your vehicle will not start, there are a few things that could be the issue such as a dead battery, a bad alternator, or a bad starter. It could even be a bad sensor or a stretched or broken timing belt. If it is the starter or dead battery, you will hear a click when you try to start the ignition. To determine which it is, you can use a voltmeter to check the battery. When the vehicle is off, it should show 12 volts. When you turn the key to start the vehicle, it shouldn’t drop below 10.50 volts and if it does, then it is most likely the battery.
