Hello,
If you are having issue pumping fuel into the tank then it is typically due to a clogged EVAP canister or a faulty vent valve for the canister.
If the fuel tank is usable to vent during fill up, it will cause the fuel to build up in the fuel filler neck and trigger the pump to shut off.
The EVSP canister is located on the top side of the fuel tank (see diagram).
The vent valve solenoid is located on the fuel filler neck (see diagram).
