Vrs struggling to start when cold.

I was wondering if anyone had any suggestions for the problem my car has got.

I recently had the cambelt snap on my car, Once repaired i have had a problem with starting it up when the engine is stone cold.

It sounds like fuel is struggling to get through, but after a couple of seconds its fine and starts up sweet as a nut.

It also misses every now and again at low revs.

I have read about the none return valves on the fuel pump failing and air drawing into the fuel system, Its cost me an arm and a leg so far to try and sort it but still no look.

Any info would be great thanks.
