First hit some small blows (with a hammer) side and on the steering wheel, try again. But you must close the general key that should be in the tank. The cutting wrench is generally exclusive and with a few taps loosens. The other option is to disassemble the stem with an assistant, responsible for blocking the water outlet when removing the stem and keep it closed until you replace the leather
I already took the stem and the little rope is fine, I show you the photo if you can see it, I put it back and the water came out right away, for now it is going well

It was glued, there is no doubt, notice if the leather with its saucer is firm in the stem, if it is loose put a couple of turns of teflon so that when raising the stem it lifts the assembly. I'm glad and good weekend greetings
Discuss what type / brand of faucet, it could be that the "chord" is stuck in the seat
the faucet is cross type like this

I can not see the image but I imagine, cross is the steering wheel, but the faucet can be ceramic or compression closure, usually those of the cross can be with chord and yes, maybe it is stuck in the seat. You'll have to disassemble the stem and see.
