3. "fuel flashed out fast from cylinder #3" does that mean with the spark plug removed you get significant amounts of gasoline droplets spraying out of the spark plug hole? If so, that is likely a sign of too much gas, either from the CSV or the injector. Were your spark plugs wet with gasoline?

"pulled the fuel rail again ... I get 4 blobs of fuel wetness" What does that mean? Did you pull the rail with the injectors attached and the 4 blobs are appearing at the injector tips during cranking? During cranking I believe that you should get fuel spray from the injectors (best to have 4 bottles to collect spray during test).

4. "I have spark to all 4 cylinders" - How did you test this? Did you hold the sparkplug ground against the block and check for spark across the electrode gap? Really fouled plugs cannot be cleaned. If you have spark across the electrode gap then they should be OK. If you used an external spark tester that is not a guarantee that you have spark in the cylinder.

7. "I have stepped up the pressure via the fuel pressure regulator" - Don't do that. The 28-30 psi fuel pressure should be just fine for starting. It almost seems like you are getting over delivery of fuel and raising the pressure is not going to help.

8. "what should the reading be" - The values for the coolant temperature sensor and the ambient air temperature sensor are specified in the D jet trouble shooting guide which was provided in a link earlier on. If you are within 100 - 200 ohms of the value in the guide at the temperature specified in the guide that is probably good enough. The factory service manual shows a fairly large tolerance for the values.
