    just today my truck wont start first try after sitting a while. if i shut it off and try to start it right away it starts fine. if it sits i have to try twice. i bought this truck 4 years ago and it had the same problem at that time and the dealer said it was the fuel pressure regulator bleeding down and its was in the tank. they fixed it before i bought it.

    can anyone confirm this or is it something under the hood? i really dont want to dig into the tank. by the way its a 6 liter

    Try this, when you first hop in the truck, instead of turning all the way to start the truck turn it where the fuel pump comes on but doesn't turn over. Do that two or three times while waiting in between to allow the fuel pump to prime. After the 2nd or 3rd time try to start it and see what it does.

    My 03 suburban had the same problem, threw in a new fuel pump assembly and fuel filter and it runs like a champ, it could be the regulator though, not 100% sure
