Answer
Hi zacherya,

      I have alot of diagrams but don't know the year, make and model of your car. What I might suggest is to remove the battery cables and make sure they a clean and not corroded. Then tighten them both back up and see if the engine will start. If it doesn't then maybe you have a bad battery or one that needs to be charged up. Let me know if I can be anymore help. Bill
