Fgx2015

I made 354.6kw with stock fgx turbo

Upon inspection the fuel pump doesn’t show any signs of leaking I have noticed the relay box in engine bay makes an unusual sound with ignition on once the fuel pump stops priming it’s like a ticking humming sound

Would this problem allow it to drive for 3 weeks without any issues

So I was driving and out of nowhere it starting spluttering and not wanting to respond pulled over car stalled out went to start and the first time it nearly fired now it just cranks and doesn’t fire at all can hear the fuel pump prime when ignition is on and smells like un burnt fuel recently got tuned and all supporting mods including walbro 525 fuel pump has had new filters and plugs trying to fix it myself before booking it in to the tuner any ideas ?
