Re: Rough Start
Instead of turning key on for 5 seconds, turn it on and off twice or three times and then start the truck. If it starts right up, you have confirmed the problem. I dont know where the check valve is in these fuel systems, but most vehicles have a check valve of some sort to keep the lines primed with fuel.
Mine is 2005. I am surprised a 2007 is doing this.
Post back if you get it fixed and what they specifically replace.

I used to change them about every 20k on my old Avalanche and on my Tahoe.
