I started my 2008 Expedition XL. The check engine light was on and the steering wheel felt locked. I turned the car off and now it will not start. The engine turns over. In fact, when releasing the key it continues to turn over. The car has been running fine with the exception of the driver door power window being slow in the cold. I don't believe the 2 are related, but I have no idea. Thoughts as to what the problem is? Thanks
