If it doesn't even run on low boost 0.1/0.2 bar as you said you probably have problems with fuel

I had a problem once, I was on the motorway doing 150 kph and then had to to lift off the throttle:engine cut and never fired up again.

The fuel regulator(black thing on the left side of the fuel distributor) had gone stuck while decellerating (fuel cut-off) so it didn't get any fuel

Changed the regulator and all was perfect again.

Maybe this is not working properly on your car.

Swap it with one of your friends cars and see how it does?

BTW have you checked the fuel pressure and capacity(how much it delivers)?
