Well, air shouldn't be the issue then.
The problem just come up out of nowhere? Next thing I would do is get a fuel pressure gauge on it and check pressure while cranking.
Opti hasn't got wet, has it?

The opti was replaced 10K miles ago with the water pump. I am pretty sure it is okay.
Kind of strange, when I was driving it home, and i would acclerate a little hard (not wide open) it felt like it was choking very slightly. Any chance it could be a bad injector?
My injectors are original with 110K miles.

I have never ohm checked injectors. Can you describe the procedure? I am guessing that you uncap the wires from each injector and then measure the resistance? What is acceptable range?

It might be hard to do an accurate test though, because you can't get your hot.

the acceptable range on a multec 1 is 14-16 ohms. however if you find one under 10. unhook that one and try to start. A shorted injector will shut down the ECU. Even if you have 2 shorted it will start with 6 injectors if thats your problem. Watch the video in the sticky
