2000 Chevy S-10 Four Wheel Drive Manual 140000 miles
My s10, with the zr2 package has an engine code that says secondary air pump malfunction, I have pretty much checked the wires and connections, checked the 30 amp and 10 amp fuse behind the battery and all checked OK, when I start the engine the pump located under the radiator will not come on, how ever, you connect it to the trucks battery and the pump will still come on, does the pump run all the time, or just some of the time? If the pump was the problem would it come on with a battery connected to it and still be faulty, Any help with this would surely be appreciated, Thank you.
have the same problem?
