I have a 2001 5.3L Z71 sierra with 70,000 miles. I recently took it for a smog inspection and it failed throwing the code P0410. I checked the fuse, it's fine, at start up the air pump does engage then stops after about 15 seconds. Could it be the EGR valve? How can I go about trouble shooting the problem?

Do you know any place they can be purchased. I checked the local auto parts stores and they don't seem to carry it. Do I have to go specifically to the dealer to get the pump?
