"No que nos querías ayudar"
I think this means don't you won't to help us maybe in a sarcastic way but I can't understand why it starts with No que?

¿No que ?
The expression ¿No que ? communicates surprise at a change of plans.
¿No que ibas a salir? Didnt you say you were leaving? (From the looks of the situation, I have concluded that youre no longer planning to head out.)
No mames, cinco órdenes de alambres. Said by a taquero after getting off the phone with the customer. The other taquero replied: ¿No que cuatro? Wasnt it supposed to be four alambres and not five?
¿No que muy valiente? Werent you saying how brave you are? You dont look brave now.
¿No que ? works nicely as a response when someone has let you down. ¿No que íbamos al cine? What happened? Werent we planning on seeing a movie?
So kind of a "didn't you say/indicate you wanted to help, so where's the help".
More simply a "didn't you want to help?"
I don't know if derived as such, but adding an "era" between no and que would seem logical:
No era que... Was it not that.
