Hey there,

I've just noticed in the last week or two that when my car is running, and then I shut it off, it makes this weird "pressure releasing" hissing type noise after I've taken my key out of the ignition and the car is completely off. My friend (3rd yr apprentice) said it could be an evap sensor (or something like that...?) or the fuel rail...anyone else have insight into this strange noise?

Likely the fuel pump pumping fuel back to the gas tank. Use the search engine and you will find a few threads about this.
