P0203 Code

[Davejb]

2011 Speed 3 began missfiring.
I'm getting an error code "P0203 Injector Circuit Malfunction - Cylinder 3". We have checked wiring to the injectors and it all seems ok. Checked resistance at injector 3 and it was the same as injector 2. Has anyone had issues with this code and found a way to resolve it?

What is your fuel pressure when it misfires?

I’ll have a look when my son gets home, is there something specific I should be looking for?
