Gordy:
easy way to check the ignition switch:
* Buy new ignition switch ( recommend oem)
* remove knee bolster.
* Pull ignition switch connector off installed ignition switch
/lock cylinder.
* connect new switch to connector
* Use screw driver to try new switch.
If you starting problems are resolved, then its time to pull the switch.
If not, your problems are elsewhere and you just save the 4+ hours to
R&R the installed switch
