2012 Dodge Avenger 160k miles, 2.4L

I've had a few issues recently I'm not sure what may be relevant or not but I will include a quick summary.
* The battery and alternator went out about a month ago, replaced both and everything worked fine.
* Then a couple of days ago the passenger side window stopped working and I've been dealing with that but haven't fixed it yet but troubleshooting leads me to believe it is the window motor. However the drivers side also seems slugish now.

I'm up north and these winter storms recently have the temp down in the teens. This morning when I got off work it sounded rough when starting it. A check engine light came on while driving home P2173 I found when reading it with the OBD.
I went to start it about an hour ago and there was a single pop noise and now the car won't start. It attempts to start over but won't. I couldn't be more stressed right now as I have no clue as to what happened. Any help is appreciated.
