    when the check engine light comes on due to a secondary air injection pump code the following has most likely happened. the check valve(s) have failed causing exhaust gas to enter the pump and blow the 30 amp fuse(located under the battery holding tray)the solution is to check the pump with jumper wires to see if it stil works and it should.remove and replace the check valves then replace the 30 amp fuse.reinstall the battery and drive.

    Replaced the fuse to the left of the battery(have to remove battery to change) and the problem hasn't came back. Its been about a month since this fix, but the car sees very little driving. The fuse is a 30 amp and its under a plastic cover in its own little box.

    I still have not fixed the problem, but I think it is damaging the catylytic converter as well.
