Hello,
 

I had to change ECU in my Omega B and after that car won’t start. I changed immobilizer too which I bought with ECU. Moreover ‘’check engine’’ light doesn’t light, fuel pump doesn’t pump petrol into engine... After I connect OP-COM , I can’t diagnostic engine but I can only immobiliser. 
New ecu is from Opel Vectra 2.0 16v X20XEV 1998 ECU Simtec 56 02

I can’t diagnostic engine

 

no engine light = ecu not responding, no voltage
