has anybody checked the lift pump pressure and volume? these trucks run fine with a failed lift pump till someone runs it out of fuel then it rears its ugly head because it will never fully self prime and the high pressure pump is now straining to pull the fuel all the way from the tank through the dead lift pump.you need at least 17 p.s.i. feeding the high pressure pump.very common problem.another is the ground connector by the negative battery post,follow the cable you'll find it.clean it good.I'm not talking about the battery terminals,this is a big ass connector!check all the grounds you can find.second guess would be t.p.s. glitch but I'm just guessing here cause I can't scan it and there's no codes right?.....happy huntin'
