The fuel pump controller is in the back under the spare tire plastic carrier. There's actually a NHTSA recall out (NHTSA Recall ID Number: 22V955) for an issue that would cause your problem. It seems that water can accumulate in the volume underneath the spare and cause problems with the fuel pump controller. There's a post about the recall here.
