The clutch disc is probably stuck to the flywheel. Once the timing belt is done, you might want to get the car to a large parking lot or empty street and get it going (with the engine warmed up, shut it off, put it in gear, restart, depress the clutch as you are rolling) and repeatedly nail the throttle, let it off, repeat as necessary. That should do it. Be sure you have room to do this!!!! HTH, John
