Clutch pedal assembly requires excessive foot pressure needed to finally get starter to turnover

Have to push the clutch down very hard to floor to get the starter to engage and turnover. It seemed like it was excessive foot pressure needed to finally get starter to turnover then it just stopped turning over with it all the way to floor...few months ago pedal went to floor, and I reattached pedal assembly under dash and it worked fine until it won't start now.
