This afternoon, i went out out town with GP and when i came to start him again, the ignition switch LOCKED just before sending current to the starter!!!! It turns all the way from ACC. to ON but NO IGNITION!!! I've looked EVERYWHERE around and under the dash, i've even dropped the column to check the switch that is bolted ON it but NOTHING!!! Would it be the lock mechanism inside the column???? That little mechanism with the little sector and a rack???? THANKS!
