Okay so my car has always made this noise but it's getting progressively louder. Right after I shut off the ignition, there is a rhythmic pumping/gulping/sucking noise for about 30 seconds. Fuel pump maybe? I have no clue what it is...if you really listen, you can hear it in this sound file.(the video wouldn't fit)first you hear me turn off the car and then it starts. It sounds like it's coming from just the other side of my instrument panel
