Replaced the fuel pump tonight and the car started right up!
And I did figure out the other weird symptoms: A few months ago I posted a long blip about idle trouble and poor fuel efficiency. I cured those problems by cleaning the throttle body, replacing the PCV hose & valve, throttle body O-ring. It ran fine with that, and then I came across a coolant temp sensor so I switched that out, and thats when the fuel pump went kaput.
I should have, but didn't think anything of that sensor. When it started today, it idled at 1800rpm and the CEL came on for the coolant temp sensor. Comparing new and old sensors, I saw the numbers were different. I refitted the old sensor and reset the CEL, and it immediately idled 850 or so. So, I guess broken fuel pump + wrong coolant temp sensor = no start and weird symptoms. I appreciate all your input and I'm glad my saab once again runs as smooth as can be.
