Denali Takes Long Time To Start

[jwrape]

I have a 03' Denali and when you turn the ignition on, the motor turns over but it takes many rotations to start. It just started doing this in the past 2 weeks. There are no codes and it doesn't drive any different but it kinda studders for a second once it starts.

It's almost like the fuel pressure has bleed down or something and it is taking an effort to get the fuel up to the rail or something.

Any ideas of what I can check??

Thanks

Pull the vacuum hose off the fuel pressure regulator on the fuel rail and see if there is any fuel inside. If there is, replace it. If not you probably looking at a fuel filter or pump.

Is the Fuel Pressure regulator on the fuel rail?
