The gas is not getting through.
The information provided for you Chevy Corsica is unfortunately a bit limited. If your problem is the ability to pump the gas into the gas tank itself, you may want to try pulling back the black accordion portion of the fuel nozzle on the gas pump and attempt to slowly pump gas into the gas tank. If you run your gas tank too low, air and gas fumes take up the empty space and trigger the cut off on the gas pump to stop pumping to prevent overfilling. If your concern is with fuel getting to the engine, you may have a tired or failing fuel pump. It is also possible that the fuel filter can be clogged or perhaps the fuel injectors aren’t functioning properly. I would recommend enlisting the assistance of a certified mechanic, such as one from YourMechanic, to come by and take a look at your Chevy Corsica. They will have the experience needed to determine the source of your Chevy’s issues and replace the fuel pump if required.
