I think you're asking which of the three is correct.
None of them sound quite natural in English, but it's difficult to say without any context. Can you explain what you're trying to express? In what situation would you say it, and to whom? If it's a reply to something, what did the other person say to you?
-do that job.
+I dont want to
-I dont ask you do you want or not. In other words, I dont give you a chance to do that or not.
I wish I could explanied sufficiently.
