clutch problem help please

clutch, pedal, problem, minutes, thing, awesome, advance, disengage, floor, replaced, bought, slave, cyclinder, pressure, pumped, line, presure, resevoir, full

so i JUST bought my 91 mr2 n/a and the clutch doesnt disengage, pedal to the floor... nothing.. so i replaced the clutch slave cyclinder... and still nothing, there is no presure at all in my clutch pedal. the resevoir is almost at the full line but there is still no pressure in my clutch pedal, i even sat there and pumped it for like 20 minutes and that didnt do n e thing to help. so if anyone can help me out and maybe tell me how to fix the problem that would be awesome. thanks in advance
