I cannot Fill my 09 Yukon XL Gas tank

[galant102]

Hello I am new to the forum if this question is in the wrong location or if there's a sticky please tag the url for me ty. I am trying to figure out why I cannot fill my gas tank past 3/4 full. I have done some research and I am assuming its pointing to the Carbon Canister. my question is what can it be if my truck is not throwing any codes she just will not fill.

Not venting through the canister be my guess
