I will check the cold start valve for function this weekend. If the CSV checks out I will move to the fuel accumulator. What would be the best test for the fuel accumulator?

I haven't considered the check valve(s) because the problem only exists on full cold starts (8 hours or more parked). I would expect the condition to be present for any start after even a couple hours down.

Time to study on the manual.
