Hey Doc...Here's a couple of ideas. Get a voltmeter or test light and be sure the battery is in fact fully charged. Check the condition of the ground cable from the battery to the shock tower. I have seen two that were broken and it wasn't visible. If the headlights come on then you can rule out the ground strap. If not, then the battery is not connecting to the electrical system. Also, consider the ignition switch. Do the courtesy lights come on when the door opens?? If so, then it's probably the ignition switch. Hope this helps..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
