lost power. do a tuneup, ever read the op guide and do the 60k mile tuneup? the 60,000 mile service schedule as it is called.? can be cause by bad spark or lost fueling. only completing the tune up , can you blame fueling. if it is fueling, then start with pump pressure. (gages) no tools , no joy.! no tools, big wasted money guessing.
The fuel gage shares the same fuse as all the gages, so if the fuel gage is inop and all other gages are working then you have another problem. The most common cause is that the sending unit for the fuel gage inside the fuel tank is defective, that is true 99% of the time in my 35 years of repair work.
The fuel sender unit and the fuel pump take the power from the EFI fuse.
The fuel gage takes the power from the gage fuse.
Operation: the fuel sender unit has a float device that measure the fuel level and send the measurement in volts to the instrument cluster, the cluster contain the fuel gage.
The gas guage does not have its own fuse but instead gets its power from the "integrated power module" that handles power delivery to the entire instrament cluster and beyond. If the guage is in-op,[doesnt work] then you will need to have a few "hands-on tests run to verify if the sending unit in the tank[fuel pump module] is functional or if this problem lyes else-where, wiring problem, bad ground,ect,ect.. One hint would be if the low fuel level l;ight still functions without the fuel guage working,then your problem is NOT in the tank and very likely is in your dash-electrical or faulty guage.

One fuse operates all the gages, so no the fuse is not the problem, the problem is that the gas gage sending unit (a variable resistor) that senses the level of fuel in the gas tank is defective and needs to be replaced, this is the most common problem with any fuel gage problem
This is a great car but I has a few crazy lil things that are a pain. The sending unit in the gas tank needs to be replaced there is a polarity issue with it. Here's the kicker the fuel pump and fuel gauge sending unit are made as one piece so you must replace both. see http://www.oreillyauto.com/site/c/detail/DPH0/FG0115.oap?year=1999&make=Pontiac&model=Sunfire&vi=1357174&partType=C0401&parentPartType=C0025
