94 Ford Ranger clutch has no pressure

My 94 ford ranger after replacing the fly wheel which was missing three teeth, now has no clutch pressure, we've bled an entire bottle of fluid through it and done exactly what it says to do in the manuel for bleeding clutch system and still no pressure. Could there still be air in line or could it be somthing else? Clutch was working befor the flywheel was changed, and everything got put back in the same way it came out.[/B]
