Hard to start after sitting.
When i let my truck sit over night or while i am at work it is hard to start. After i have been driving and only turn it off for 5 min or so to run into store it will start right up. It runs fine when i get it started just seems like i am loosing fuel at motor. I have replaced fuel filter already made a little difference but not much. Possibly the fuel pressure regulator?

    yes, but the pressure regulator is integrated into the fuel injectors system, so you have to replace your fuel injectors.

    Fuel pressure regulators are known to fail they are under the upper intake plenuim on the injector assembly you can service just the regulator seperate but you still have to get to the injector assembly first. It is just clipped to the assembly.
