01 Tacoma 3.4l hard to start

My Tacoma has been hard to start for months now. Basically if the truck has been sitting for a few hours then it takes several turns of the key to get it started each lasting a few seconds. So basically 5-10 seconds to start. After it gets started the initial time then I can go to the store or whatever and it will crank right back once I touch the key. Normally after it has been sitting over night the truck will crank the first time but sometimes it won't.

Normally when the truck cranks it white smokes pretty heavily so I am assuming that it has fuel leaking down into one or all of the cylinders. To that end I have changed the fuel pump, the fuel pressure regulator, all 6 injectors and even renewed the starter for shits and giggles. None of this has helped.

I don't think that it is water leaking into the cylinder as I have kept a pretty close eye on the level of fluid in the radiator and it has not moved. I also seafoamed the crap out of the engine and cleaned the MAF sensor.

Does anybody have any ideas because I'm completely stumped?
