Kinda misfire help

Hi everyone, the last couple of days I've had a little issue, the old girl has gone from starting straight away just on the key i mean just a flick of the key to struggling like she has a missfire. Once she's running she seems fine no loss of power or anything. Has anyone had anything like this or know of anything like this or what could be causing it. Any help very much appreciated. Cheers

Will it start if you do the purge cycle first? If so it may well be air in the fuel system. Usual suspects are bleed valve in fuel filter housing or injector seals.

Thanks for the reply I'm gonna try the fuel purge before I set out for home
