1996 Volkswagen Cabriolet car turns over but wont start

Hi,

Last year, after letting my cabrio sit 3-4 months out of the winer, my car would turn over, but not start, so I bought a new battery and it still turned over but didnt start. I brought it to a mechanic and it ended up being a fuel pump fuse.

Now, my car has been sitting a month in the really cold weather and is giving me the same problem. It turns over, but will not start. I would like to change the fuel pump fuse but I do not know where it is located. I thought the mechanic said it was under the hood, but if so I have no idea where.
thanks!
