Engine starts with starting fuild, G4 and G28 tested, and fuel spills out from fuel line while crnaking the engine. Injectors wire also tested. Is it the problem of the G40? I have not test G40 yet because I not sure how to. Is there a posibility of faulty fuel pressure regulator?

Definitely could be G40.
The ECU needs to see the G40 pulse at exactly the right moment TDC in the cyl 1 compression stroke.
So if G40 is not working or cam belt has slipped or a cambelt pulley has moved and the cam timing is not correct, the engine will not start.
So check the sensor is giving an output, you can DG o this with a LED.
And Check timing using the marks on the flywheel and cam pulley (RS2 timing mark lineup is weird, should be half a tooth out, do a search)Last edited by newsh; 2 August 2020, 10:46.

Have you reconnected the fuel lines correctly? Have you tried starting without the maf? Is it just flooded? Remove all spark plugs and blow out fuel with air line. Allow to dry and then try again. Is the battery fully charged and turning engine over quickly enough? Do you have bad petrol? Work your way through the link above methodically and you will get there.Nothelle S2 Avant

Do you have a labatory power supply? Just pull out the injector and apply 12v to them. They should make audible click.
if this is not the case, i think your fuel pump has died.
if engine runs with starter spray you are clearly missing fuel.

I got the fuel injectors tested and serviced today, put them back and engine starts right up. And random stalling issue is also gone. It seems like the injectors on the RS2 can be blocked esaily if car sits for a while. The posts I have seen on this form regarding the ADU engine no starts issue are all due to the dirty injectors. Thanks for all the replies!

Ethanol in modern fuel degrades over time and makes an organic sludge.
There is 10% Ethanol in all 95 oct fuel in UK now.
Make sure to use at least 97 which should have max 5%, Esso 97 has zero ethanol in most areas of the UK at this time, not sure how long for though.
