The battery on our '05 TB started going dead after sitting for a few hours. First thought a bad battery cell then I caught what sounded like a vacuum cleaner running in the intake. I researched on here and then founf the fuse for the punp and pulled it. NO MORE DEAD BATTERY! Now the pump wants to run all the time when the fuse is put in though and this morning it finally did kick the check engine light. I've pulled the relay for the pump but it still runs with the fuse in even when the relay is out. Any ideas with help is appreciated.
