2.0 Tdi starting problem

[BellS3]

I have a 2010 2.0tdi
It has an intermittent starting problem, engine turns over but doesnt fire, have plugged it into vcds and have noticed there is no fuel pressure when it wont start.
Anyone know if there is a relay that could be faulty or any other ideas?

There is a fuel pump relay, without checking your car specs, usually it's hidden with others above drivers footwell behind the big trim.
