Well, don't forget to check the basics, such as the fuel filter and the tank screen.

If you're a real cheapskate, you can try the "Geoge Murphy" fix. Remove the fuel pumps from the car. Using a battery, some tubing, and a pan of solvent, jog the pumps _backward_ while running solvent through them. George recommends diesel fuel. I suppose mineral spirits would work OK too. No guarantee, but I have read of this method curing a number of pumps - they spit out lots of nasty black crud, then run fine. Perhaps worth a shot if you have more time than money.
