Default Motor cranks but no start *help!* (with video)

Hi,

First of all i did do my research and i am leaning towards it the solution being a camshaft position sensor i just want further opinions.

(2006 STI, car is stock)
So my car started to have longer crank time before the engine started and now its to the point to where it doesnt start at all.
It does have gas and does not have a CEL light on. It cranks strong and i hear the fuel pump working.

With no CEL light it is still possible the camshaft position sensor is the problem?
If so i read that the sti engine has 2. Which one would it be? or both?

*here is a video of the last time it "started" : View My Video
( sorry for moving the camera around but i thought the car started and got ready to turn the video off but it didnt)

please ask any specific questions and i will try to respond right away.
Any input is greatly appreciated! thanks!

I've never heard of a cam position sensor keeping the car from starting, especially without an accompanying CEL. Usually it either throws a CEL or it makes the car cut out above about 5k RPM. Have you checked your fuel pressure? When's the last time you changed your fuel filter or cleaned your MAF?

I have not checked the fuel pressure. And the fuel filter? you mean the one connected to the fuel pump in the tank? Unless its covered under the 30/60k maintenance i have not changed it.

Thanks

I would second fuel pressure. Are you able to get a learning view? It might show how the fuel trims have been leading up to this.
