If cleaning the terminals for corrosion doesn't fix it, then we'll try something more. But first a couple of questions, 1) Is your ignition switch wired the same as mine with the same colors at the same terminals? 2) Do you have a traditional points/condenser ignition or an electronic ignition, like MSD. If you happen to have a MSD ignition, and it's under the dash above the passenger's feet, take a quick look under there and tell me if you have a big MSD capacitor next to your MSD box. Then, jumper a temporarily bypass wire from the big positive side of the starter solenoid to the left screw of the #1 fuse. Assuming it doesn't immediately heat up and start smoking, check to see if your lights now work. If they do, see if the car will now fire up and what now works and what now doesn't.
