Ran out of fuel so it came in air in the high pressure side. First Ive got just 150 bar on the common fuel rail but when we startet to bleed the injector we came as high to 400-500 bar.

The car dont start but its came some puff on starta attempt.

How high will the pressure be before to start?

Any other ideas how to bleed the system if there still some air?

Normally, after say a fuel filter change, it is just a question of turning the ignition on and off two or three times and letting the electric lift pump in the tank resupply the HP pump. After that, it should be self bleeding.

As you ran out of fuel, if you can't get it to run, it might be worth removing the lift pump from the tank and checking the pick up gauze is not clogged, particularly as it has presumably scavenged as much as it could from the tank.
