Why did my car not start and does it sounds like a battery issue?

Start at the battery. Check to make sure battery terminals are clean and tight. Make sure the ground from the battery to the engine block is tight and clean. Check connections in power distribution box under the hood.

I have to be honest, it sounds like a loose connection. The alternator isn't doing anything with the engine off, so we can't check that. It may have allowed the battery to go dead. That is why I started there. What I need you to do is this. First, take a volt meter and check how many volts the battery is producing with the key off. It should be around 12.2 or a little more. Then, have a helper turn the key to the start position while checking to see if there is a change in voltage.

Let me know what you find. NOTE: You can use any type of volt meter to do this as long as it reads DC voltage. Don't worry, you won't get shocked. However, if you touch both sides of the battery with anything that conducts electric, it will short and spark. Just be careful if you have a screw driver near the battery so it doesn't touch both sides.
