No pressure on brake pedal?

Just bought the truck for a couple hundred bucks
Had some noise in the brakes. And the pedal seemed kinda mushy but still functioned.
Took of the wheels desperately needed pads and rotors.
Replaced them. Topped off brake fluid Now the pedal has almost no pressure with the engine running.
I can pump up pressure with the engine off but with it on I have nothing.
Ran out of time today before I could bleed them any ideas in case that's not it?
Master Cylinder maybe?
