Did you have no brake pedal before you started? Or after? Also did you bench bleed the system before you installed it? Either way it sounds like there is air inside the brake ABS system which needs to be removed to get your pedal back. This must be done with a scan tool.

Please check out this video below:

The only other thing that can be causing it would be a brake caliper that is frozen on its slides, so please remove the tires and inspect the slides.

This guide can help as well:

Please go over these guides and report back.
