I have only had a no start condition twice. The first time was the ignition amplifier, and the second time was the NTC temperature sensor on the top of the manifold. I don't think you'd have spark if it was the former. Wet plugs could be symptomatic of a bad NTC sensor, because a defective sensor would be telling the fueling computer that it is 40 degrees below zero and dumping boatloads of fuel into the cylinder so that the mixture is too rich to achieve combustion. The part is about $40 and is a good thing to have a spare of even if that is not your current problem. You might also try removing it and cleaning the business end off. Sometimes they perform poorly because there's a build-up on the sensor. I think there's a resistance check procedure in your Bentley you can pursue.
Lack of fuel pressure seems like a possible cause too. It is my understanding that it should spray out when cracked after trying to crack it. If you've got an extra injector laying around you could have a look at your fuel spray too (better have a fire extinguisher handy too). I don't hink having a shop test your fuel pressure is terribly expensive, but you've got to get the car to them. You might check with a tool rental place or Autozone/Advance Auto store and see if you can rent the tool.
