Bad Red Sheep....you never mentioned what year your truck is. There is a TSB for the P0191 that fixes the fuel rail issue and the battery temp issue. Mine freaked out at a light...got it started just long enough to pull into the dealer. They had to reflash the ECM...problem solved. Sometimes its not always hard parts.

Steelhead01...I looked a that little wire described on that thread...wasn't worn through, but covered it with 1/4" fuel hose anyways. Good thread guys!

You know...I thought there was a sticky for them, but I could be wrong. TSB #18-022-07 is the one that applied to my truck...Do a search on it or Google it. It changes the rational function of the fuel rail...they even boosted my fuel volume with their scan tool. The rail would not recover fast enough and eventually it tripped the ECM. They wrote it all up on the work order I received from the dealer.
