Well that was interesting just been over to Techieboy and tried it on his car, 3.4bar (thanks for that)
Interesting...
3.4 bar is also not standard for a Z22SE, as that should be 3.8.
Great. Now you've got me paranoid. 
Car hasn't been started for months and it was fine. Now it's been fired up and my fuel pressure is apparently too low. And you all wonder why I can't be arsed with it.

That 3.8 figure is pump running engine off, yours if perfect, should be 3.3 idle

I had an issue ages ago with a fuel pump. Give the car a damn good thrash, it ran fine. Turn it off to cool down and wouldn't re-start. A little while later started fine. Weird. Turns out the pumps get hot, Turn off and the fuel cools the case. The case gets too tight on the innerds and it essentially seizes. Cools a bit more and it frees up again. Could you be suffering something similar?
That's what I am thinking as well

Ah, ok.
You normally check the base pressure with the regulator disconnected from the vacuum, but 3.4 @ idle vacuum sounds ok.
