Anyone needing this diagram, email me at [email protected] and I will send you a .pdf file containing it.

I'm in the middle of repairing this right now on my 2000. I noticed that in addition to the two anti-theft bolts that need to be removed, there is another bolt on top of the SCLA that when screwed all the way in, is supposed to align with a hole in a rotating assembly that is inside the steering column. I believe that if this is not aligned, then it won't hold the lock in place and when you turn the steering wheel you might get the behavior that you are seeing.

you need to bleed the system, turn key to run postion then wait two seconds and turn off again do this a dozen times then hold foot pedal to floor and crank engine, this will clear fault codes and prime system then it should start, if you need more help post here for more information.

This is for the ignition switch like you are asking for:
