I think there is some kind of electrical fault with my Mz6

It will only fire & sometimes will start on 2 cylinders. (number 1 & 4)

There is diesel going to the injectors but no electrical signal to number 2 & 3 to inject the diesel.

Has anyone had this problem or know the cure?

Regards

Mich

I don't know anything about these cars but I would think the first thing to check would be the wiring from the ECU to injectors.

What method have you used to identify no electrical signal to the injectors?

I have a spare injector which which I have tried from the supply pipes from the fuel rail with the lead for each cylinder connected.

It will inject diesel on 1 & 4 only

I have checked all wiring & can find no faults
