Clutch will not disengage. Plz help
2003 170k miles
It started by being a little difficult to get into gear. Then really hard untill it just wouldn't go into gear anymore. I was able to pump the clutch and ease into first and float it on home. I changed the master and slave cylinder. Still not disengaging and the pedal would stick. Tried adjusting the pedal a few ways and still not releasing the clutch but I could get the pedal to come back, however it wouldnt hit the switch to start the car. I am not 100% its bled correctly but sure seems like it but it doesn't feel right on the pedal. You can see the slave moving the fork maybe 2-2.5 inches but ill if its enough to release the clutch or not. It was never slipping and heard no bad noises when driving at all. Never ripped on hard it just makes no sense to me. Pumping the clutch pedal fast let's me slowly starts to release it enough for me to move into first after awhile and allot of pressure on the shifter so it makes me think master or slave still but they are new and i think bled right but maybe not....

Welcome- but from your description, it sounds like you've still got a clutch that needs bleeding. It's clear you've tried several times, but are just not sure you bled it correctly. I'd suggest you bring in a pro to take a look. Replacing a brake master usually means a bench bleed before installation will help. Also, at 170K, when did you last change the clutch? It would be a shame to get it all properly bled and find the pressure plate or other clutch component is shot.

If you don't have full service records for your Z, at least ask your buddy about the clutch. The clutch master is NOT a regular component to fail, so you may have other problems in there. Be sure to come back on here and post up what the problem was when you get it figured out.
You may try taking off the slave cylinder and compressing it, then bleed while compressed. Reinstall then bleed one last time. I had a hard time bleeding mine quite some time ago before doing this method. dkmura's advice about bench bleeding the master is sound as well. Hopefully you did this.

You still haven't mentioned when the clutch in your car was replaced? If you're saying your buddy "hasn't had any clutch issue" and never replaced it- you're asking for trouble by not doing it at 170K.
And yes, I'd bench bleed the master (when everything else is installed).

I thought I said he had not done the clutch yet but at 170k im sure its been done before. Take the cover off for the fork on the bellhousing and looking inside looks perfect. For the very first time ever I just don't have the time to work on my car so I sent it to a Nissan dealer near me it'll be the very first time since high school paying for work to be done but at least I'll know it'll be top of the line and also give everything Else a good check. I will be back with what the answer is as soon as possible thank you all for your help!
UPDATE: I had two other guys and a trans shop look at it too no avail. Took it to the dealership and found out its the pivot fork SLIGHTLY bent and a part of the pressure plate broken off. I gave the go ahead to just do the whole clutch job and mayne even the flywheel. Its the first time in my life paying for work and it feels like magic😂
Hope they do the upgrade on the clutch fork while they are at it, these forks were known to flex in early models with heavier clutches. If yours has on it in. Would recommend a stronger pivot ball but nissan doesn't have one.
it's getting nissan clutch, fork, throw out, rubber line from slave. They wouldn't warranty the part if its not theirs, I asked about that id rather have the warranty. Should be out of the shop by tues/wed
I got the Z back last night!!! Clutch was basically toast along with broken fork. All was replaced and feels like NEW! hopefully my troubles saves someone hours of trying to bleed. Thanks everyone who put in their thoughts!
