I have the same problem, there is no pressure when i push down the clutch i got a brand new master slave cylinder and slave cylinder and pumped and pumped let it bleed and still no pressure on the clutch and no air out when i open the bleeder.

 

when this happen to me I found that under the dash there where the clutch pedel connects to the master cylinder rod there is a plastic clip yup plastic dumb as hell but ford did it. youtube has a video on it its under CLUTCH PEDAL FIX FOR FORD TRUCKS by powerstrokehelp
