i had the same prob, check the fluid in your clutch I think yours is hydraulic.... if you have a leak in the master cylinder for the clutch it will leak when it sits, if the fluid is low or drained then fill it up with fluid and then push the clutch by hand up and down if it wont come back up yet and it should be back up........ did you check the fluid? if not check it and see if that was the prob, you know where its at right?
