Have you pushed the airflow meter flap down while having these fuel pressures. If no fuel flows under those conditions the problem is in the fuel distributor. If it only doesn't flow at rest then thats the way its supposed to.
Your lower chamber pressures should be .4 to .5 bar lower than the upper chamber pressure. Disconnect the EHA and check the differential pressure. You have only .2 bar differential press right now and that could easily keep the car from starting. You should have about .4 bar with the EHA disconnected (electrically).
Tell me what happens when you push the flap down.
