Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello! Two other equally common parts for this vehicle that can cause this issue are the canister vent solenoid and the canister purge solenoid. I'm assuming you don't have a smoke machine to test for leaks so you could start with those. The purge solenoid is under the hood and the canister solenoid is next to the evap canister under the car.
Just a heads up I will not be available this evening so I will be checking my messages in the morning. Have a good night!
Any progress on your equinox?
