What is your question?
The truck sputters, misses, dies at rest. It seems to not be getting proper fuel. Could it be a fuel filter, pump,relay? It's been to a repair shop and they said that it was the knock sensor. I'm not sure how they determined that yet. I'm going to try to find out.

Have you or a local technician near you hooked up a fuel pressure gauge to the fuel rail? Getting real data is far better than a guess. I wouldn't guess at "knock sensor" either -- even if there is a related code set, it means check the system out and figure out the whole picture, don't just guess at a single clue or code or symptom. www.repairpal.com/repair-shops
