    Could be a lot of things. Where are you located in Wis? I am south of Milwaukee. Does the check engine light illuminate on the dash? Is the security light flashing? Is the start or crank fuse blown?

    Could be a bad starter relay in the under hood fuse box. Pop the relay and see if there's power on one of the terminals when you turn the key to crank. If there is suspect a bad relay. There are also fusible links that could be blown. Also bad grounds by the battery and on the trans. I guess there is power to the relay at all times if the fusible links and fuses (more than one) are ok. Good luck and let us know what you find out.
