Bleeding the clutch systems can be a bear at times.
There are 2 ways. One is with a vaccum bleeder. You might be able to rent it at the local autoparts store.
If not the other way is the way you have been doing it. But im going to give you some hints.
First you need 2 people. Next what you need to do is with the bleeder closed have one person in the car and have him lift the clutch pedal off the floor and bring it to the top. Than push it down to the floor and hold it there. dont pump it 3-4 times just do it once. Also it may be easier to use your hand since teh pedal probably has no spring to bring it back up to normal height. Now with the pedal on the floor open the bleeder for a few seconds and than close it. Than repeat the process. Honestly i can tell you this will take you a good 10 minutes of repeating it till you get some sort of resistance on the pedal.
Once you have resistance you can than start to pump the clutch pedal 4 or 5 times and than hold it to the ground. Than open the bleeder.
The problem is that once the clutch master has air in it its a pain to bleed the air out of the master. But stick with it and you will get a pedal.
