HAVE TRIED EVERY THING I KNOW CANT FIGURE IT OUT ANY HELP WOULD BE AWESOME THANK YOU
The fuel pump in the gas tank and the fuel pressure regulator are what controls fuel pressure-the pump builds pressure in the lines and the fuel rail on the engine, and when pressure is correct the pressure regulator keeps it constant by controlling the fuel return line from the fuel rail to the tank.
If your fuel filter is clean and not plugged, it sounds like the pump or the pressure regulator needs to be replaced. Even though the pump is working, it may be weak and failing. Some vehicles have the FPR inside the tank with the pump-You will have to check where yours is located. If it is located on the fuel rail, it can be checked to see if it is working right.
Good luck.

i would try a fuel filter first. the fuel gauge going crazy is most likely the sender they go bad and eventually stop working. the bummer is you have to replace the fuel module. these aftermarket are about 200 bucks. the module comes with the pump and sender which is the next part you want to look at. gm has some issues with the harness to the fuel pump externaly. it actualy will melt and start to lose conection. i would check this by visualy inspecting the plug on top of the tank. unplug it and take a look. if it is at all disscolored replace the pump (module). the new pump comes with a replacement harness (make sure its in the box)hope this helps and good luck
