Hello everyone, I'm having a little issue with my truck sometimes not starting right away. I got it down to when it does it maybe someone can point me to the right direction. If I start it in the morning or if it's been sitting for more the 6-8 hours, it starts up perfect. The problem happens after I use my truck and let it sit for about 15 minutes, after that it takes about 2-3 seconds of cranking to start up and I have to give it a little gas for a couple of seconds so it won't turn off. It only does it at thoughs times and my truck runs perfect after it gets started, no missing or bogging. So far I tried spark plug, fuel filter, even a new fuel pump (Delphi brand). I took it to a mechanic and he told me my fuel pressure is a little low but just a little bit. It does the same thing as with the old pump so I don't think that's the problem. The fuel pump even sounds strong when it startss pumping. I hope someone can give me some advise on here. If it helps it has a 4.8L V8.
