Space ship noise from pump in summertime? I had posted this several years ago but forgotten what the answer was. I have an irritating noise that occurs in the warmer periods of the year. It sounds like a space ship is trapped in my exhaust/engine 
. I know that sounds silly but that is what it sounds like. It doesn't occur if my car sits overnight but if I drive somewhere in the heat, let it sit then start it up again I hear it loud and clear. I was told it is some sort of pump for air or fuel or something? If you know what I'm talking about could you please post a pic of where it may be located. BTW I can hear the noise in the engine bay and as well as coming right out of my exhaust.

yeah thats the air pump lol mine made that same noise. it injects air into the exhaust manifolds to pre-heat the cats. yours might be malfunctioning because they should only do that when the engine is cold. the pump is under the drivers headlight area. find it and unplug it to see if it goes away.
