Help with brakes before I pull my hair out

You may need a scan tool to bleed abs. module. Had to do on 2007 escalade

Yes, I am using a scan tool to do the autobleed sequence.

Just a quick update:

Over the weekend I received a replacement master cylinder and an ABS valve block. ABS valve block is put to the side but on hand in case I need it, can be returned for full refund.

I bench bled the master cylinder perfectly until no compression (realistically just a teeny tiny bit but that's normal) and put it on the truck.

I'm curious about this? I've bench bleed tons of master cylinders. but this doesn't sound familiar? what do you mean by no compression? the internal piston should he compressed completely till it bottoms out. the last little bit of air in that front res is always the hardest to get to.

Of course. What I mean is I prefer to use a kit with hoses so I can be sure no more air is circulating. I prefer this over the "plug ports and pump until air stops rising into reservoir" method since it never works for me. BUT, when I am done, I remove the hoses and install the provided plugs for installation so I don't have to worry about dripping. Once they are installed I can now also check for any compression which should be none. Basically, bleed master cylinder, plug off ports, now piston can no longer move. If air is still trapped and the plugs are installed, I would be able to compress the piston still. Kind of a clunky explanation sorry..
