Ok. Replaying my own post.
So far i have found that air mass meter is gone. Checked wires voltages etc and output voltage is pretty low.
It's decided not to start and when it's not starting there is no fuel rail pressure and after cranking for longer time it's bringing up immobilizer and communications faults.
Found that it's needs new high rail fuel pump ,needs attention to brake pads wear sensor wiring.
Waiting for customer's answer now.
