Since it wouldn't crank over at first, check all connections at the battery, between the two positive cables especially. The corrosion on the spacer between the two postives might be preventing connection.
Did you mean temperatures were 20 deg below zero when you said -20s?
But first, since it's at home, pull a plug wire and lay it on the engine metal while someone cranks for you and see if you have spark!
Then check the battery voltage while cranking to see if it drops below 10 or so which is the minimum needed for the computer systems to work.
Then use that fuel pressure gauge you borrow from Autozone or elsewhere to check pressure.
You need fuel, spark, and air for it to run. The fuel may need to have higher pressure at crank so the Fuel Pressure Regulator might be a factor, but that would show in the pressure test.
The fact that it wouldn't even engage the starter at first makes me suspect the cables at the battery or a defective battery. Then after some attempts, the battery or corrosion warmed a little and changed and you got a connection for cranking power to the starter.
Since you are in a cold wet climate, the ground buss under the door sill edge/carpet might be a factor. I do not recall people saying that caused starting problems. You might try pounding that area with your heel to see if there is corrosion on the buss preventing ignition from working.
Good luck.
