i tried bleeding my system cause that's what i figured was wrong with the clutch. now when i try to bleed it when i push the clutch pedal, no fluid comes out the bleeder, and resevoir level doesn't come down, i repeated this bleed method about 30 times and it won't bleed out any fluid. sometimes it's hit or miss with it sometimes it will and sometimes it won't bleed any fluid, most of the time no though. i can't build any pressure with the clutch pedal.

my bleed method as follows.
open the bleeder vavle with the clutch pedal not pressed in. the press in the clutch, clutch stays at the bottom, close bleeder vavle, move the clutch pedal back up, open bleeder valve and press clutch pedal. etc...........

you got the process wrong.

you need to pump the clutch 3 to 4 times and hold it down.
open the bleeder valve and let the air and fluid come out (prob. for 5sec. or so)
close valve and if you have a lot of air, pull up the clutch pedal and repeat it over.

i did that now, and it sound's like the slave cylinder won't prime no matter what i try, i tried bleeding the air out several ways, and even did it the way subaru told me the way that you told me nothing has worked. if i push down the clutch it just springs down to the floor, and it sounds like phhhhhh, and it sounds like it's coming from the slave, but it might be the suction, im thinking so because when i leave the bleed open and push the clutch no fluid is coming out, so im thinking that the master cylinder is toast, the resevoir isn't moving no matter what i do
