Rob;
I just checked the cut-way view of CSV in green manual to see if there is an internal final filter (as there is in the cyl Injectors)...my thought is that if this filter was totally clogged, even if you had Fuelrail pressure, and you applied power to CSV winding,(and it was free to operate), this filter, if clogged, could still completely impede fuelflow...result of looking in manual: ...it is not absolutely clear (and labeled as a filter like for the cyl Injectors), but it does look like there is a final filter present in the CSV also...so if you verify that TTS is supplying power to CSV and it is not flowing, this is another possible reason which could prevent fuelflow...simple fix is to blast in carb cleaner and catch what is flushed out on a white paper towel for inspection.
Good Hunting!
