I just got my new steering column in the mail. Turns out my steering column was cracked, so nothing would line up right. The ignition pin is probably what's stuck. You just undo the screws and pull the switch off the back end first. Then the pin, then the tumbler. It's quite simple actually. I've been starting mine with a screw driver for almost a year. Finally broke down and bought now parts I found someone parting out. If the pin is just cracked or broken, the replacement part is fairly cheap, but if the column is cracked, you'll have to find a new one. Anyways, the only hard part to remove is the tumblr itself. When the key is turned to the on position you can remove the tumbler easily. If not, it's a little bit tougher. pm me if you need some help. My guess is your pin broke.
