I just recently purchased a Chevy S10 with 116,000 miles, standard transmission for my son. It failed the emission test on "Secondary emission". The mechanic did a diagnostic test ($100) and told us that The AIP Pump fuse is blown. Found water in the AIP pump assembly and the AIR pump failed. He said he found factory service bulletin to verify AIP pump failure and recommends a new air pump for the cost of labor and parts at $598. I feel after the price of the diagnostic test that took all of 10 minutes he's scamming us. Could it just be the fuse needs to be replaced? Or could another filter be causing the emission test to fail?
have the same problem?
