Charles, I agree wholeheartedly with enough thought no Superduty will be 100% theft proof. And also that a rollback will take care of business almost without exception. That being said, if I was stealing cars and was having trouble getting a Superduty started, I'd just go to the next house, the next block, or the next neighborhood. There are so many unprotected Superduty's out there that it doesn't make sense to fight a single truck, unless that particular truck is really worth it for some reason. You and I both know that a semi-experienced car thief could steal an unprotected Superduty in 20 seconds or less.
On edit - I nearly missed your comment about the fuel pump, and I agree 100%
