I am hoping for some general advice on this one.

I have only carried out basic tests as i do not have access to a scope or a scanner that will give me any more than P codes.

The van was running on 3 cylinders and has had a new injector fitted.

The problem now is it will start and run on all 4 cylinders but cut out after a few seconds.

I disconnected each injector in turn to try and narrow it down and it will start and run on 3 cylinders without cutting out no matter which injector is disconnected. It is almost as if the ecu is unable to drive all 4 injectors at the same time, i have checked multiplugs and loom at ecu.

Hope this makes sense, thanks
