Have checked all fuses on the management side. When activating the relay it pumps fuel. Will scope the injectors to see what they are doing. I assumed that if the ecu does not see the power coming fom the fuel pump relay it would not fire injectors? Otherwise how would it know if the fuel pump relay is working? I shall scope them and see whats happening but by the fact it doesnt run I am suspecting they are not firing.
Had a look through archive on here last night and found an astra with a similar fault and was apparently a common failure on these ecus for them to drop the negative switch to fuel pump relay so I am strongly thinking in that direction.
OP com is a cloned version but hasnt given me any grief up until now. Upgrading to proper version shortly though as its such a great tool.
I agree that the ecu is the last thing I wanna change and that all other avenues have to be checked first!
