Also when you depress the brakes will you get any pressure? and if so, can you pump them up only to have your foot sink to the floor again? And I'm sure you have checked and have no leaks right...
And here'* where I say " I'm still stumped "

Mount the master in the car

pump the pedal about a million times
remove clear tubes and hook in brake lines

You must bench bleed the master before installing it in the car and then bleed it again from there. Check the instructions that came with the master cylinder.

I replaced the master cylinder on my Lesabre a couple of months ago and let me tell you, even bench bleeding the cylinder took a lot to get the air out. On top of the roughly 20 to 30 full strokes they recommend, you will also need to tap the cylinder with a hammer to get the air out, and if in doubt - stroke some more.
If you look in the bag that the plastic fittings and bleeders came in, it should explain the need, and technique, to properly bench bleed the cylinder.
Cheers,
