No check engine light but having problems fueling up on 2004 Denali XL
I have not had a check engine light come on, but had an issue with my '04 Denali only taking about 0.3 gal before the pump clicking off like it's full. I replaced the CANISTER PURGE SOLENOID VALVE and it seemed to solve the problem...but only for a couple of weeks. The problem is back!
