2000 Grand Prix Secondary air pump

Hi All,
I have a 2000 Grand Prix GT 3.8L

My secondary air pump finally went after 8 years and 103,000 miles. When I brought my car to my mechanic he replaced the pump as well as did an conversion kit to re-routue the intake.

Well I have replaced this pump 4 times already...and each time it was replaced my mechanic told me he found the pump filled with water, now just for the record I don't go swimming with this car...nor do I drive thru all the puddles in the road.

I just got back from the 4 th pump bieng replaced and when I shut the car off the pump just kept running and wasn't able to turn it off unless I disconnected the battery.

So I just disconnected the pump.......HAS ANYONE ever had this problem with this pump before.......?????
Is it possible whatever tells this pump to go on is broken......To be be honest I don't know what this pump does...
:banghead:
Any help would be apreciated.....

The moror is constantly supplied 12v and the comuter controlls the ground to turn it on/off. Check for a short to ground on the ground side of the motor.

The air pump pumps fresh air into the exhaust to more thouroughly burn all fuel that may make it out of the engine.

I didn't know GP's have air pumps. Mine doesnt (that I know of).

Take it back to the initial mechanic and have him check out his ductwork.

The secondary air pump was for LEV III emissions certification and whether your car was delivered to and sold in a green state. New York is a green state and basically follows California emissions control standards.

There is a GM TSB out that covers adding a plastic protective shield to the pump so it doesn't suck in water.
