Answer
Micheal,

It's possible the two are related.  Because if I'm not mistaken you have to engage the brake pedal in order for the key to turn.  If you tighten it to tight, it might not be hitting the switch like it should when you press on the brake pedal.

So try loosing the switch again.  Loosen it back to where it was, then try to start.

If it doesn't work, you will probably need a new ignition switch  or ignition (both the same).

Try that if it doesn't work let me know, I might have something else in mind.
