Well frist of all is your check engine light on? Sounds like a problem with your EVAP system. Sounds like it's not venting like it should. Take it to the shop it needs diag. Most likly it's the vent solenoid or a kinked hose.
Good luck

having problems filling up my sons 03 sonoma 2.2..every time...EVERY time we go to add gas it just keeps stopping...takes forever just to get gas..is this a easy fix...single mom here
Here is some news, bad or good. S10 has a length of rigid pip from gas cap, downwards TOWARDS tank. Then there is a piece of rubber pipe, from ridged pipe to gas tank.
Remove the hose clamps from both ends of rubber pipe. Remove the rubber pipe. Use a flashlight and mirror to see through gas tank fitting. The fitting you can now see because we removed the rubber hose.
The S10 has spring loaded shuttle that travels up and down this fitting. (about 4" of travel) As gas would pour in to the gas tank, the pressure of the gas will push valve (shuttle) downwards allowing gas to empty into the gas tank.
This spring loaded valve, was designed to prevent gas from being stole (syphon) from tank. This is a poor design by GM as dirt can get stuck between shuttle and the inside of plastic fitting on tank.
The shuttle may be stuck, by a piece of dirt, floating in gas. Pushed the shuttle in toward the gas tank, then let the spring push it back and work the shuttle back and forth. When your finger pushes the shuttle all the way in, you will feel the hole where the gas would pass emptying into the tank.
If this does not work, you can lower tank, and remove shuttle all together. This would leave no restriction in the filler pipe. Here is the recommendation from GM.
Good luck and be safe. please keep us posted.
Fuel Spit Back When Filling Gas Tank - leak.
When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.
Condition/Concern:
Customer may comment when filling fuel tank, the fuel spits back.
Recommendation/Instructions:
To correct condition, the following steps should be taken:
Verify that fill limiter vent valve/rollover valve is not stuck closed or open (Fill limiter vent valve/rollover valve is part of the fuel sender assembly).
Verify that fill limiter vent valve/rollover valve is not leaking.
If neither of the above conditions exist, blow air through all lines including fuel tank.
Blow air through EVAP canister.
Attach the rubber hose portion of filler neck to fuel tank first.
Attach fill neck to vehicle.
MAKE SURE THERE IS NO KINK IN RUBBER HOSE PORTION OF FILL NECK.
Put new gas in the fuel tank.
Verify that vehicle is fixed before returning to customer.
Fuel spit back can also be caused by the fuel vapor pressure being too high in the fuel tank or high fuel temperature.
