I must say that I am surprised, the check engine light should have came on if that solenoid failed... Interesting it didn't, well computers what can I say. I too am having an issue with pressure build up in the tank, Chrysler engineers so graciously placed a black fuel tank directly at the rear of the vehicle, behind the axle and exhaust. It is always nice to unscrew your gas cap and hear PFFFFFFF!
