Need Help,,,

Autozone diagnosed "Service engine soon" light is caused by secondary air pump.

So, I have it replaced and the light was turned off. Pump valve and hose were not replaced.

But, the light came back. I still can hear loud noise coming from the pump for a minute on a cold start in the morning, which is a sign of failed pump I learned this website.

Why do you think it is not OK? What should I check? It seems but I doubt that the new pump does not work.

Thanks a lot.
