Fuel guage is working, this is our delivery van for our florist, so its been through a lot of feul this past week,ran low daily. Its a 2005 with the 3.8?
its the larger of the engines.

3.3 and 3.8 are virtually identical so there is no need to discriminate there.

U codes are body control codes. They are near impossible for a do-it-yourselfer to diagnose and repair. Normally, they require a dealer level scan tool and a good knowledge of advanced voltage testing to properly diagnose and repair. Most likely, there is either a bad wire or BCM. You could repair a bad wire yourself but the BCM would require VIN flashing and that takes a dealer scan tool or the van would go into theft mode. My two guesses are just that, guesses. This problem will need someone with a dealer level scan tool and proper tools.
