nice, i just had this problem with my car. heres a list of things to do.
1. check and make sure the master has a locking bolt on it, the reason cause when you pump the clutch ill lock it so no air get in.
2. pump at least 10-15 times than bleed it, it should build up pressure, and make sure you do it fast.
3. check the lines and make sure no air is gettin in it, if so replace it
4. bring it to a mechanic
so there could be a few things wrong with it, you just have to mess with it for a while
