I have had this truck to the dealer and a fuel screen was changed and the egr valve has been replaced. When it is hooked up to a camper it acts like it doesnt want to go. The engine light comes on and the code is for low fuel rail pressure. I was also told there was no lift pump. Do these trucks come with a stock fuel lift pump or not? And would one help my problem? Any help will be grateful. Thank you
I had the same problem it turned out to be the injector pump witch gm covered it.

fuel filter had rust found, only after low fuel rail code. dealer reset and didn't help. Fuel filter rusted out according to dealer? He advised water in fuel but unable to prove without water. Fuel pump metal nipple rusted and contaminated the system. Water in fuel system didn't work and now trying to get GM to pay.$4339.00. Has anybody had this problem.
