Ignition rack problem? (ignition problem has gotten worse)

[JacobSchni]

I saw this page when i was looking up solutions. First off i had it where when i turned my key my truck would not start on its own. but when i turned it and used plyers to pull the rod it would start. i figured i had to adjust the ignition switch, but im guessing its the rack now. tonight it wouldnt start. when i turn the key the rod doesnt move at all. The key just turns with out any resistance and noting turns on(radio, then the start postion) its just loose. I can still start it if i pull the rod manually, even without keys in. Then to turn it off i have to push the rod back. Would this be a problem with the ignition switch rack? Any help is great.

heres a post on a similar issue post i saw:
