Won't start after fueling or oil change.

The DTC (diagnostic trouble code) will tell you exactly what is wrong 9 out of 10 times. I strongly suggest that you invest in a OBD2 code reader or have someone who has one read the DTC causing the CEL (check engine light). Many auto parts stores will read the DTC for free. If you have a smart phone there are free and very inexpensive apps that will allow you to read and clear the DTCs using a cheap bluetooth OBD2 adapter.

Examples:

Torque for android
Dashcommand for ios

... or we could guess, throw darts at a list of possible causes, etc.

This sounds like way more fun. Couple more beers and I'll have some very interesting causes.

Seriously...get the codes read.

I'll start!

My guess is that it has something to do with the CEL.

Hopefully. I've always had great success with OBDII DTCs pinpointing the problem, unlike OBDI where there would often be multiple DTCs and you had to guess which one was the actual cause.
