My fuel gage goes to empty even when its full and continues to go up and down

I have several fuel fuses n two fuel emissions fuses could it be one of them?cuz even w the tank fuel even while driving the fuel gauge goes from full to empty constantly

Only way to be sure is to check those fuses and check wiring for proper grounding! Otherwise, suspect fuel level sender is failing.

Thank u ok i checked fuses all are good so it must be what u said cuz now the gage doesnt even move at all but now i have a throttle problem how do i reset my computer system cuz now i have a eng pwr reduced

unhook the negative battery cable for a few minutes to reset the computer.also on your car you can just replace the sending unit/float/switch,but the tank has to be dropped and fuel pump module assembly has to be removed from the tank
