For me, not being a mechanic just someone that fixes their own cars, as far as I know, the emissions equipment in these cars does not start operating until the engine has warmed up, so I'd doubt if a Lambda sensor fault would ever stop a petrol engine starting.

Just found it.
Its probably fuel pump because i inject start gas in intake manifold and it start runing
Maybe i just need to check fuel preasure.

Okay!
So you will still have a pre cat Lambda sensor, ie B1 S1 to replace sometime to stop that "17588" fault being logged.
Do you know how much preasure should it have on fuel pump.
Plenty of people say 1bar of preasuere
isnt that low?

I think that the running pressure at idle should be a lot higher, there is a pressure regulator in the fuel filter assembly, maybe check which version is suitable for your car and that would let you know what the design maximum running pressure should be.
