there is a star publication for the gas tanks due to a failed vent in the tank that will cause the vehicle to stall when the tank is above 3/4 full.. also the wiring was changed in the older vehicles to use the newer fuel pumps and that requires the old harness to be re pinned/spliced with a new connector. takes like 10 min to re wire. also this is a general star publication. would need vin to verify if it is covered....
