My 94 was doing that when I bought it from Marty. Took the fuel pump out and the strainer was clogged and completly flat. Put on a strainer from a 97 (it was free) and that problem is fixed. I'm not saying that you need to use a 97 strainer, but I would check to see if your pump strainer is clogged or flat. It should hold some shape since it holds around a tablespoon of gas in it.
Also, since you have a 92, the baffles may be falling apart inside the tank. A 92 owner (or somebody with more knowledge on them) should chime in on this.
EDIT: Sorry for hijacking, do a search for '92 gas tank' and you'll probably find a lot of info.
