the ignition switch and the wires to it from it may have chaffed thrugh the insulation. you must open the column up and see whats melted. then check the fuses .. I would check any after market crap installed ... but since this is quite old even the GM wiring gets damaged after this long. many times people slice into GM wiring with wires that are very small current capacity. then the fires begin..
