About 3 weeks ago it got very cold, -20 my fuel lines froze up. I got it into our shop and thawed out, drained the gas out replaced with fresh and water remover, changed the fuel filter and spark plugs. the truck will now start and run rough, if i step on the gas hard, it wants to die like it is being starved for gas, if i give it gas slow it will rev up. i have been checking other threads and found one that refered to the FPR (fuel pressure regulator). i pulled the vacuum line and gas came out so I replaced it. now the truck will start and run rough llike before, but when it gets warm and i turn it off or it dies, it wont start again until its cooled off. It acts like it is vapor locked. I released the fuel pressure at the fuel rail by the injectors and alot of air comes out not much fuel. I followed the fule line to see if it was near the exhaust, possibly causing fuel evaporation in the line and its not. if I spray some gas into theintake it will fire and run till the gas i sprayed is gone. please help thank you
