1.4 tfsi starting issue

[2011A1]

2011 1.4 tfsi 122bhp

sometimes starts fine, sometimes has to crank a couple of times ?? timing is fine, fuel pressure is fine, new high pressure fuel pump has been fitted had the timing chain swapped aswell these things havent stopped it, i find its worse when its been left for a few hours inbetween starts start/stop seems to work fine!! sometimes a tappety noise on cold start aswell, please comment if you have had similar issues, please dont comment if your just suggesting one of many things it could be 😂 as im looking for actual experience with a similar issue, also dont think its an injector as the fuel pressure is fine and theres no hesitation through the revs. 

any help is appreciated thanks in advance 👍🏻
