Question about 2000 Pontiac Montana
Yours must have the California emission system. They use a secondary air injection system to help reduce emissions. It could be that the pump has gone bad. Have you tried to reset the code? I've seen cars that had this problem and just to erase the code took care of the check engine light. If that doesn't work, make sure your electrical wires are ok, and plugged in. Check to make sure you have voltage at the plug at the pump motor, you may have to start the car to check it. If there is no power there, then check your fuses and relays.
