when my fuel pump went up i could hear it while i was sitting in the drivers seat. sounded like a lawn mower in the distance.
another handy tip i didnt know when mine died, sometimes you can give it a nice tap with an open end wrench or something like that, it may start pumping again. it could get you a mile down the road or so. in my case, i could have gotten it home, i was that close. . .
