You didn't do a good job then assuming your just trying to bleed the system.

You don't need a battery charger just be sure battery is in good shape. The pump runs for about 12 minutes.

1.Ignition on, engine off.
2. Temp to 84*
3.Fan to lowest setting.
4.Gas pedal floored for 10 seconds.
5.?????
6.Profit

You'll hear the pump kicking on after a few seconds.
