I'm so frustrated with the evap and fuel sensors in my Yukon! I have had the evap filter cleaned out about 8 times, and had the tank dropped and everything cleaned out twice. I even paid for the GM kit to reroute the sensor under the hood. Whatever my mechanic does, I might be able to fuel once no problem, otherwise it takes about 15min at the pump! Any ideas?
thanks

Gotta ask, but have you tried using different pumps?

do you mean fuel pump? No, I will try that.
thanks!

Do you mean pumps like gas stations? Or pump like my fuel pump in the truck?

Are you getting codes? What codes do you have? EVAP codes are the biggest pain. A vacuum leak can cause problems and they are a huge pain to locate.

Yes, I was talking about using a different fueling station pump. I was having the same problem with mine awhile ago. (bonneville)
