does the pedal go straight to the floor, can you feel anything in the pedal(feedback etc.)if the clutch is brand new, it might be you didnt install the throwout bearing the right way or the pivot fork isnt making contact.if its a new unit, and the clutch it bled properly, i'd say your problem is inside your bellhousing. probbaly going to have to take it down again and investigate.

i know you just installed the clutch so it probally wont be the same problem i had a few months ago.

but when i couldnt go into any gear with the car on it was because a clutch spring popped out and was stuck between the clutch and pressure plate.

the clutch has a little bit of pressurenot much at all.. and there was nothing wrong with the pressure plate the only thing was that the throw out bearing holding cup was chipped a chunk was gone but not too bad..

sounds like your pedal doesn't have enough pressure, sooo you either didn't bleed it correctly,your master cylinder is bad or something fell off during install.

dude also bypass the clutch block, it makes bleeding the clutch way easy because then there is only one place you have to bleed the clutch at.

sorry man, i think you are going to have to take it down and see if the throw out bearing its in correctly and such...and like somebody here already said maybe that fork looking thing is making contact correctly

replace both master and slave cylinder, your lines, and remove the clutch damper box. Then report back.

Could something be wrong with your pedal?

If the problem happened suddenly while driving, i would guess that one of the springs on the clutch disk fell out and jammed itself in the pressure plate.It happened to me while i was driving on the freeway a long time ago in the first car i owned.I down shifted and then accelerated to pass some cars and when i went to upshift, i noticed that the clutch felt funny and it wouldn't go into gear. I drove the car back home and replaced the clutch in a carport using a skateboard as a creeper.
