Same problem as above with the pump running after the car is turned off. Mechanic told me it was the ECBM control module. Gm wants $1100 but you can get them rebuild for as little as $150. Do a google on ECBM module repair.

This is the issue that brought me to this site. Just happened today and had no idea what that noise was. Looks like it's going to be expensive.
