I have replaced the master cycinder, that didn't help so I went down and opened the inspection plate where the slave is and I tryed to pry the clutch fork to see if it will disengage and no matter how hard I pry I can not move the clutch fork. I just put in a clutch disk and this is whats happing. What could it be?1993 isuzu trooper

 

Im not very educated on these cars but is it a hydrolic clutch? and does it have a slave cylinder?

I ask because first you might need to bleed your clutch, second if you have a slave cylinder and its f**ked then you will have to replace that.
