Avalanche brake failure

A friend of ours, not me, has an '02 Avalanche that has no brakes at all, he replaced the master cylinder, yes it was bled, but the pedal still goes to the floor and wont even pump up. No leaks anywhere either.
I bled the master cylinder for him and it had a good firm pedal then but, when the lines were connected, nothing, right to the floor, I'm stumped. Could it be the ABS, module, pump or sensors?
