I looked around and couldn't find anything that could help me so I am posting hopefully this isn't already answered. So heres my story

1991 240sx s13 ka24de.

I went to start my car about a month ago and the clutch was fine i started to take off and the clutch dropped to the floor and didn't return, i then pulled over and stayed in first and rode it back home (was only 2 streets down). I checked the fluid and i was bone dry, weird cause i never noticed a leak or anything. I then filled it and bled the clutch, still no pressure to return the clutch back up. so then I replaced the slave cylinder and the master cylinder, while I was replacing the slave I noticed that the clutch fork was pressed in and stuck (couldn't move it even with slight tapping of a hammer) so then that led me to believe something was wrong with the trow-out bearing or clutch fork spring. I then take out the transmission replace the clutch and pressure plate along with resurfacing the flywheel and new throw-out and I noticed the spring for the clutch fork was out of place, so I bought a new one at the nissan dealer ($2.98). I replaced it all and mounted the transmission up yesterday. i bled the clutch a little today to where I was getting a very small amount of pressure along with a good stream of fluid being forced out of the bleeder valve. I would get a little bit of pressure but that was only if I pumped it fast. I still need to bleed more but my question is does this all seem normal? should I have any pressure or any sort of return when pressing the clutch? I believe the clutch pedal spring is still good. I will bleed more tomorrow but just curious if I need to bleed more or if there is something else going on. Thanks guys.

Have you bypassed the clutch damper box/loop? That thing is the devil incarnate.

Also, did you check your pivot fork bolt while you were in the trans? Its semi-rare that they break, but they do (it happened to me :( )

I had the same problem when first getting into my build i removed the damper box thing that papsmurf is talking about and then it was all fine.
