If the regulator jams shut then that would force all the fuel through the injectors causing them to flood.

Try pulling fuse 18 and try starting it. If my thinking is sound, then it should start to prove the fault... Failed ecu temp sensor has a similar effect but that will throw a code :-\

I pulled 18 (pump fuse) n the car fired up again. Jay! ;)
Finally some hope again.
As the car oviously gets flooded now.
What is most likely causing this?

Injectors not closing? ( cleaning or bad ecu?) (i have a spare working ecu)
Jammed pressure regulator?

I consider remove injector rail with injectors to se how the operate. Guess i could connect Them to 1,5 battery for just test opened closing movement and clean Them up.

Given the lack of codes, I would start with the pressure regulator :y

Cheap enough and easy enough to swap out :y

An new pressue regulator at opel Garage here in norway is 170gbp "insane" iknow!

Order a used regulator+rail+4injectors from ebay gm genuine for 45gbp instead.

Bad injectors leaking defective will not give codes aswell. (Only short circuit)

1 week waiting for update! :)

Problem fixed!!!

The car now runs normal again.

Think it was alot of diffrent fault causing this. (no codes)

Summary:

Car didnt get fuel but spark.
New pump, new fuelfilter cleaned fuel lines.

Car got fuel spark but too much fuel.
new fuelrail, injectors, and pressure regulator.

And now the car is normal again!

Think it was the fuel regulator causing this.
Probably because of bad fuelfilter. The filter at fuel regulator was pretty clogged.

Thanks for all replies!

Regards!
