I just had my ABS repaired, installed it put the fuse in and the pump isn't running all the time. The ABS light is still on and the ABS is not working and no codes are reading. I did disconnect the battery for 20 + minutes. Any thoughts.

 

You can't clear ABS codes by a battery disconnect. The pump should only run when the ABS is doing it's antilock thing, like one wheel locked up and the others turning or very hard braking.
