Hi about 3 hours ago i got into my car to come home for a friends house and my ABS light came on as i touched my gas pedal after i started the car. I figured it was a false sensor warning. When i went out to take the trash out 10 min ago i noticed my car was making a Vibrating/Humming noise. Ive heard about some type of pump for you ABS system or motor. This really worries me as i dont want 2 have a dead a dead battery in the morning when i got to school. PLEASE HELP ME!!

I've never heard of the ABS pump activating after the car was shut off. 
In fact, my ABS pump only activates after I start moving (following a previous ABS engagement) after start-up.

The only thing I can think of is that since you got an abs warning light one of the abs valves is leaking and you were hearing the pressure slowly bleeding off. The noise may also be a vacuum leak in or by the brake booster. I don't believe the noise what ever it is electrical.
