Firstly.............LOVING the pointy pictures

Right.......the 3 unions you indicate, show there is fuel pressure.

Now, you won't get fuel out of the actual injector pipes unless the flap is being pushed down (thats how the fuel is metered).

So, you could try, making the pump run non stop and gently pushing the flap, and you should hear the injectors spraying (don't do it loads you'll flood the engine)

Personally though, i'd whip the air box/filter off and crank the car over and look to see if the flap bobs up and down, i would almost guarantee you have an air leak!! In which case, the flap won't move
