Battled the familiar misfire p0300 and p0421 issue (non fouler is awesome!) and jacked up the cats in the process. I dropped new coils, plugs, wires, and EGR and the car runs good, except for the hesitation due to the clogged cats, I ordered a new exhaust header and mid pipe \cat to deal with that.
My daughter has been driving it for a month with no issues or error codes. Yesterday I find some time to take on the exhaust and go to start it in the nasty -20 windchill cold. It cranks but won't start. This car had zero starting issues previous to this. ECM has no stored codes in it. I have a BT OBD2 reader and a smartphone if you have ideas.
Here is a video of the issue.
Tried to Jump it - same result
Tried starting fluid - same result (only did this twice with a two count of spray. Not interested in blowing it up.)
checked the fuel pressure on the return line - squirts out just fine.
I ohm'd the Crank and Cam position sensors, both look fine.
What is that sucking noise that I hear?? What ideas do you all have?
I'm going to go back out and go through the basics Spark, compression, fuel, once the -30 windchill goes away. Until then I figured I would throw it to the internet and see what you all say.

I'm going to chew on the last that PCB posted and see what I can find. I'm also going to drop a new battery in this. It tested okay, but it's 4 years old and as I might of mentioned earlier, it gets a bit chilly here. I'll keep you all posted.
