2001 GMC Jimmy cannot bleed rear brakes?

[alex f]

So my problem started after a brake hose (front right) burst on my Jimmy. After replacing it, I went to bleed the brakes on the vehicle. I had a bleeder screw break on the right rear caliper, so I replaced it. While bleeding the brakes again, once I got good pressure at the caliper, I had the main front-to-back brake line burst right above the gas tank. Yay, I love rust. So anyway, I bent all the tubing myself and installed it, but now when I go to bleed the rear brakes, I get absolutely no brake pressure. I disconnected all of the line running from the rear, including the one coming from the ABS pump (much easier to get that front flare nut off), when I replaced the line and now I don't get even a drop of fluid coming from the ABS pump. The front brakes have excellent pressure.
I'm at a loss for words regarding how horrible this vehicle has been for ultimately what should have been a simple pad swap, but whatever.
tl;dr: Replaced rear brake line, no brake pressure coming from ABS Pump, how do I get my brakes working again?
