Intermittant P0268 - help please

I am getting an intermittant P0268 code, injector circ hi cyl3. How are the cylinders numbered?
I am guessing this is probably a wire harness issue under the valve cover.

Any thoughts or ideas?

Ok, just looked at it and realized the injector wires run externally. I could not find any spots where the wiring had rubbed. The code is coming up with my spare ECM installed with Robs fuel economy EFI tune. I put the original ECM back in and put about 50 miles on it today with no problems. Must have an injector driver in the ECM going bad.
