pretty sure theres only one fuel pump... when you turnyour car to accessory you should hear the fuel pump pressurize. (keep the door open when you turn the key to hear it) is that the sound your hearing when the car is off?

My friends truck does that, it sounds like that right after you shut it off, it does it for like two seconds. It is something under the hood shuting off after you turn your car off.
