I've had some troubles starting my 1986 F-150 XLT Lariat. I can turn the ignition without a key, due to a break in a few years back, and it is very hard to turn the ignition. Even with it being difficult, I can turn the ignition on, but it will not turn the engine over. I'm trying to figure out how difficult it is to replace the ignition cylinder, or if anyone else has had a similiar problem I'd love to know about your experience with it.

 

Correction, it's an '87, didn't notice the mistype before.
