So when I got my car it didn't have pressure in the clutch pedal at all. I didn't know what the problem was, but then shortly after I discovered the problem I found out it had a hydraulic clutch system. So I figured it was the slave or master cylinder for the clutch. I replaced the master and slave cylinder and the line that connects them. There's no leeks or anything. Its perfectly set up, but I still have no pressure in my clutch. And yes I bleed everything correctly. There is a little pressure, but not much. Then I noticed that when I press in the clutch pedal the slave cylinder doesn't move the clutch fork. I took the slave off to see if it was working correctly on its own and its functioning the way it should so its not the slave. I'm not sure how much the clutch fork is supposed to move, but it only moves like an inch. And when I put the slave cylinder on the clutch fork it extends the clutch fork as far as it can go. So when I press in the pedal its like the slave tries to push in the clutch fork, but its already pushed in for some reason. Please help
 
Does the fork move back more when the slave is removed? Sounds like you have the master cylinder adjusted wrong. Can you push the slave back in the bore with your hand? If the master is adjusted incorrectly the slave can not return all the way.

What do you mean by "adjust the master cylinder"? I just attached it to the pedal, bolted it on, and attached the line to it. Sorry this is my first car and I'm a noob. and yes it does move back more when I take the slave off

Watch the video. The clutch adjustment will be the same for your car.

Can you confirm that you bench-bled the new master cylinder prior to installation?

Just so you know:
There wouldn't be any pressure in the pedal unless you pumped it multiple times with the engine off.

Also you should be able to tell if the clutch is fully disengaged by going WOT and watching to see if the rpm's climb on the interstate (that's how I discovered mine was slipping)
 
If you've fully ensured you have the master and slave cylinders set correctly. Check the play on the clutch fork. There is the possibility that it somehow popped off the pivot ball/stud inside the bellhousing.

To test...start the engine. Push clutch pedal, try shifting into gear, if you can't, again, check the the clutch fork for excessive play. This scenario is more of an issue with getting the car into gear, but I'm not putting it past the realm of possibility.
