I have a 2003 Toyota Camry 4 door sedan. All of the lights come on but it wont turn over or start at all. Even when we tried to jump it. The radio and 6 disc CD player haven't worked in a while. I don't know why but a friend of mine was under my hood trying to figure out why my radio and CD player didn't work over the weekend. After that my car wanted to die when I would come to a stop. Now it's progressed to not wanting to start at all. All the lights come on but nothing happens when I turn the key.
