Chevrolet Colorado gas pump shuts off frequently, causing slow refueling on Chevrolet Colorado

Some Chevrolet Colorado owners report experiencing frequent shut-offs while refueling, which may be due to a clogged EVAP canister triggering the safety mechanism of the pump nozzle. This issue can arise from a vent valve solenoid that is stuck in the "closed" position, necessitating replacement with a factory brand Delco part. Additionally, a malfunctioning vent control valve within the EVAP emissions system can lead to slow refueling and repeated shut-offs. While some may assume the problem lies in a blockage between the fuel filler neck and the gas tank, it could actually originate from a part in the EVAP system that hinders proper fuel vapor collection. To resolve these issues, it is advisable for owners to diagnose and repair any evaporative emissions problems by inspecting the EVAP system components and replacing faulty parts. Addressing these potential causes can lead to smoother refueling experiences for Chevrolet Colorado owners.
