I would say its the fuel regulator. It maybe leaking down faster than it should causing the car to take a little longer to build up fuel presure to start the car. As soon as u turn the key to the on position you should hear the fuel pimp wine to presurize the systen. Get a fuel guage on the fuel system and see if it holds presure after you shut it off and while its runing.

I have also seen the rubber hose between the pump and sending unit go bad before, soon as the pump stops, the system loses pressure, causing a long initial crank time

if i'm not getting enought fuel pressure could this also affect performance and gas miliage?
