The fuel pump is brand new.

The more i read this thread and check things its coming back to a boost leak, im going to remove the front bumper and all the stone tray tonight/tomorrow and have a really good look around.

What would happen if the AFM has **** itself?

Also keep in mind the hose blowing off at an attachment point isn't the only failure mode here. It could be a rubber section split somewhere as well.

Refresh my memory on what the AFM is. MAF?

just like what they are saying do a boost leak test. you will find leaks that you wouldn't see.

Ok i dont believe there is any leaks.

Ive tried new plugs and still same thing starts with a little accel runs rough for a second and back fires.

On further checking of the timing belt it seems as though the Inlet and Exhaust are half a tooth forward, does this mean it has skipped 1 tooth forward?

Im really out of ideas right now, i Disconnected the Crank Sensor and the car wont start at all, i disconnected the cam sensor and the car starts for a sec then stalls.

If both plugged in it sounds like the video i attached, could it be AFM/MAF?
