Hey I went to start my 97 toyota avalon today and it wouldn't even turn over none of the lights would come on or anything..... What's wrong with my car lol

Your battery is dead or a bad connection at the battery.

You have a completely dead battery, or a loose connection. I ALWAYS Wear safety glasses. Put you key in & turnit to the "on"position. Jiggle the positive ( + ) Then Negative ( - )...if your key starts "buzzing" you have found the loose connection. If no change.........remove the battery, take the battery out top be tested.

First try jumping the vehicle. If it won't jump you you need to check the main buss fuse in the power distribution box (Should be a 40 amp). If that is good check for a grounded positive going to the starter where metal contact with the wire may have worn a hole in the insulation. If both are good and the inline fuse from the positive is not blown pull the alternator and have it and the Voltage regulator checked at Auto Zone, Advance auto or Pep Boys. One if these is going to be the problem.
