Audi A3 8P 2.0TDI Cranking not start

[Cjnek]

Hi everyone,


I have problem with Audi A3 8P Quattro year 2005, 2.0TDI. The owner said that immediately after the purchase the car started and the alarm went off (siren only).
After 2 weeks the car did not start, no cranking, and the siren was on. I found an alarm in the car Defa Can 800 and dismantled it. It was connected only to the sensors and the central lock . Starter kill wasnt connected.

There was also a module in the car Tele Comfort GSM Callstarter connected to webasto (adding, not original). I dismantled it too.
Now car cranking but not start. I have connection by all modules via VCDS. No errors related to communication, IMMO is OK.

I looking for schematic of ECU, and relays need it to start the car.
Best regards!

If immoboliser from factory then start, run die

check screws in under hood fuse box

Screws are correctly grounded.
Immo is original. Car only cranking.
EDIT: Solved - fuel system
