Question about Chevrolet Cars & Trucks
Sounds like evap or charcoal cannister. If your like a lot of people and funds are tight you can try unplugging all the charcoal canister lines and blow it out with low air pressure. If possible also the lines between the canister and evap Of you get a lot of dust this should solve your issue

The evap. emission control may be plugged. Check the charcoal canister and connections for bends, pinching, or crimping from tank to intake.

yes the pressure sensor in mounted in a rubber grommet on the top of the fuel tank. it could be the sensor but the only way to know for sure is have the dealer do a evaporative emissions fuel tank pressure test, they have the special tools to do this, outside shops do not. Have u tried a new gas cap, they can leak and cause the problem, in fact that is very common.

Some fuel tanks have a drain **** that will allow you to drain all of
the gas neatly. If you have a drain ****, it will be located at the
lowest point on the tank. Loosen the valve and allow the gas to
If your tank has no drain ****, you'll have to drain it by removing one of the fuel lines. The rubber hose that exits the tank at its lowest point will drain the tank fully. It will either be connected to an electric fuel pump, fuel filter, or to a hard fuel line that goes to the front of the car. Loosen the clamp on the end of the line that connects to the gas tank. Pull the hose off and allow the gas to run out of the tank into your container until it is drained completely.
