Clutch engage/disengage issue

The clutch works completely properly after you pump the clutch pedal 6-7 times real quick. That will get you in first gear and on up through second gear then again you have to pump it back up. No signs of leakage around or near the slave or the master cylinder. Pushed the pedal 4-5 times and bled off the slave, tightened it, released the pedal. Did this 3 times. No noticeable air coming out of the fitting, just solid fluid. Then tried the clutch for any improvement. Negligible at best. Which is it? Master or slave that needs replaced? When pumped up the car goes thru the gears properly, fully engaged and strong in all gears until it loses the necessary hydraulic.

Is there a more proper way to bleed the system than what I performed?

If it is the master cylinder that needs replaced, what crazed methodology is required to get it out from the firewall and get a new one installed (just getting to it looks impossible). Any special tool required?

I would appreciate any information from anyone who might have worked on one of these before. This is my first. I won't even begin to discuss the faulty EPS system that has the steering completely out now.

Thanks to all who help with this site. It's a godsend.
