im cam, a licenced diagnostic tech.
this is a common problem with these models.
problem is, its not always the same part thats the problem.
i have replaced plugged charcoal cannisters, fuel fill hoses, fuel fill vent hose, vent control valve stuck and fuel tanks on these for the exact same symptom.
most of the time it is a plugged charcoal cannister.
there is a TSB from dodge to help diagnose the problem on these.
i have included it as an attachment for you to follow the process. you will skip right to step 4 for you though.
let me know how you make out!
these components as listed must me checked, not just the filler neck.
its either the tank can breath from a collapsed breather tube, a plugged cannister or a stuck vent valve
or the check ball is stuck inside the tank and that would result in the fuel tank being plugged.
they must be checked individually
