96 A6 Quattro fuel pump

Sorry guys, I should have been more specific with my original post. I 
was asking about the pump making any noticeable noise not because it IS 
noisy, but because I cannot hear ANYTHING at all from it right now. I 
don't remember ever hearing it in the past either, but never TRIED, so I 
wasn't sure. I was hoping that under normal circumstances you could hear 
it slightly, so I'd know if it's operational or not. Since I can't hear 
it at all when turning the key or trying to start the car, I wasn't sure 
if it was pumping or not. I have a fuel delivery problem (no fuel 
getting to engine) apparently, because the car just cranks and will not 
start, but squirting a little starting fluid into the intake will make 
it start.

So, to recap, I am not getting any fuel, but I do have spark. No sound 
can be heard from the fuel pump, and thus the reason I was asking about 
being able to hear it, and asking where the pump is, and how easy it is 
to replace if necessary. Also wanted to know where the relays are in 
this car, so I can check the easiest and cheapest things first. 
Searching online I have found several different posts about location of 
the relay, one being behind a panel in the rear, one being in the main 
fuse box under hood, and one being under dash, above the area where the 
pedals are. The car is a 1996 A6 Quattro Wagon. I'm guessing it's 
probably under dash, because there is nothing labeled in the main 
fusebox for fuel pump, and the fuse box inside the car has a fuel pump 
fuse which is fine, and I couldn't find any relays or anything in the 
rear compartments. I'll have to remove the panels under the dash and 
search I guess.

Anyway, thanks for any input that you can provide. I'd really like to 
get this car running again. My other car (bmw 325) had engine failure 
recently, so I'm stuck with only my standard cab pickup, and I'm tired 
of it.
