It is possible that your sending unit is broken or that you have a frayed sending unit wire. Sounds like your guage works just fine. There is a testing proceedure in the shop manual (any of them, factory, chilton's, etc.) to check the guage, sending unit, and wire.

Figure you're getting 25 mpg (conservative), and you have about a 10 gal tank. 100 miles = 4 gal, which is almost a half a tank used. If your needle hasn't moved a bit, but the guage reacts to the ignition switch, then you either have a bad wire or bad sending unit would be my guess. Of course, if your mileage is much better and you have, say, a 12 gal tank then that changes the scenario drastically, and needles sometimes don't fall off 'F' until closer to half a tank and then fall fast. Best way to determine without testing anything is to fill up to get your actual mileage, and find out exactly what size tank you have.
