Strange starting issue

[PugLover1984]

Well I have a weird problem. First time I turn the key there is no noise from the lift pump and the glow plug light doesn't come on. The car does no start. Second cycle of the ignition you can hear the lift pump and the glow plug light is on - however it will still not always start on this second attempt (though usually does). It can sometimes take 4 ir 5 goes to start but always starts eventually and runs fine.

I've had it plugged in and the only code relates to fuel rail pressure. Any ideas? I feel there are 2 separate faults here.

Thanks in advance.
