Chris...before going nuts and ripping everything apart check something real obvious but VERY easy to miss.

Do you still use the factory floor mat or something similar? If yes....go check it right now! <img src="/forums/images/graemlins/smile.gif" alt="" /> I'll bet the mat has shifted way forward and is preventing the clutch pedal from going to the floor. It has happen to me and it made shifting difficult. And it also sometimes prevented the clutch interlock from making and the engine wouldn't crank.

I've noticed that the more miles on the clutch the closer it engages towards the floor. And the mat jamming up there won't allow it to fully disengage.
