Hey, this is Scotty. Feel free to visit my www.scottykilmer.com website and ask questions there directly via e mail or in my forum. As for your question here, it's probably just your battery, they need a lot of juice to start a car. A bad one will run a radio and other stuff but not start a car. You want a fresh battery, and prices vary by the size you need. I've been using the Auto Zone batterys for years, as they are fresh and their house brand is good. And auto zones are everywhere.
