Astra G 1.7 Diesel

[levisdj]

Hello everyone, I got this Opel Astra in today, not starting... I tried to diagnose ECU, but it doesn't communicate...checked the fuses all ok, DTC's stored in immobiliser are : B3040 and B3059 Communication malfunction on W line and No engine request received ... and on ignition the engine check light doesn't turn on neither the car with the key in the middle the car turns but it doesn't start... any ideas ?

maybe bad earth wire to the ecu and all on chassis and check big fuses
use opcom and tr reset ecu and immob with pin

Thanks for your answer, I did check the fuses, I gave secondary ground to ecu housing, nothing... and opcom does not connect to ecu, as if it was unpluged... I did mention that engine check and car with key does not light on ignition

find ecu pinout and try diagnose at dask. if no communication than your ecu died.

I found something in the FGTech documents, can someone confirm it's correct ?

Connect two braon/white wire on immobiliser jack and try to diagnose engine ecu

open ECU and see is there diesel in it, you can try to clean ECU and repair it, I have repaired many of this but it is very hard work, or you can just find other used ECU and sync immo, or get it with immobox and transponders from same car...
