Jeep XJ won’t start
 

I have a 01 XJ and my key won’t turn to accessory, the farthest left setting, when the black and yellow plug near the lock cylinder is plugged in. When the plug is not plugged in, it will turn to accessory. The Jeep won’t start whether it’s plugged in or not. All lights and wipers turn on. I took out the ignition switch pin and lock cylinder and nothing looks broken. Any ideas? Bad ignition switch? Thanks
