Steering Column Repair: 2000 Silverado ignition key stays in start position - no return spring to on position, salvage yards, lock cylinder

Question
I have a 2000 Silverado 1500 LS 4x4 with a 5.3. Automatic column shift with cruise. When I start the truck, the key will stay in the "start" position. I have to manually turn it back to "run" so my starter won't keep running. Also, when I turn the truck off, I now have power to accessories (radio, wipers, lights), just like I have the key turned to accessory. (Never had it before).

I am assuming the accessory power problem is the ignition switch, but am not 100% certain. As far as the spring back to run issue, I'm lost. I've asked several local GM techs about this, and have been told the spring function is in the electric switch that plugs into the bottom of the lock cylinder housing, or that it's in the lock cylinder housing itself! All have said they've never done this repair.  I have a new ignition switch (not installed yet), and can feel the detentes for each key position in the gear on top, but not a "spring" action - so I'm doubting what I've been told about the spring in the electronic switch.

If it's the lock cylinder housing, how do I replace that without screwing up that stupid passlock system? I read your answer on reprogramming the system on an '02 blazer - I assume it's the same procedure?  Isn't the chip in the housing? Also, any thoughts on where to find one? Dealer part only ($106), no luck at salvage yards yet.

I'd sure appreciate some knowledge on this before I tear it apart and get myself stranded because I've enabled the pass lock system! I've searched high and low for an answer to this, and haven't found anything. Lots of info on replacing the ignition switch and lock cylinder, but nothing on my symptoms.

I'm a decent troubleshooter, but would like to make certain I have any necessary part on hand before I tear it apart (the whole "stranded" thing).

Thanks in advance for the help!

Answer
Wow Tony:

Great detail in your question and I congratulate you for asking before just jumping in.  The answer is very simple though.  The spring action is indeed inside the switch you have in hand.  If you push it far enough in one direction you will feel the spring action.  It's a pretty tough spring.
As far as the passlock goes, you don't need to worry at all about it, you will not be affecting it.
the only thing you need to make sure you do is insert the switch into the housing in the exact same position you take it out.  I suggest you turn the switch in the vehicle to ACC (backwards as far as it will go) and then put the new switch in that same position.  This will help you avoid being off one to the when inserting the new one.

I think you will be fine based on how you described your situation and your attention to detail
