Won't start

[Contagious209]

Ok here's what happened. I had to move the truck so as I turn the key it gets stuck in the start position and I can hear the starter engaging after it turned on. So I quickly turn it off. Then I turn the key forward again and it turns on fine. Well after I shut it off I moved it again so as I turn the key to turn it on it wouldn't do anything. The key will go forward and back like something is loose but nothing is happening. So I removed the steering wheel to see if I can find something broken but I can't seem to find nothing. I think it's the key switch but my dad said it's not. Any ideas? I tried the search function but didn't find nothing. Any inputs?
