Won't start after fueling or oil change.

On my 08 CTS last time I got an oil change it the car sounded like it wanted to start but wouldn't. It took about 6 attempts to get it to work. The next three time I've fueled up the same thing happens. And this isn't on an empty tank, I never let it run very low. After fueling it doesn't want to start. Will take 3 or 4 tries and a pump of the gas pedal to get it running.
Once it starts it seems that it doesn't do this again until the next fuel up. I think maybe its the evaporator purge valve? The check engine light is on as well.

... 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. :)
Get out.
Could it be that obvious?
I thought the purge valve involved dropping the tank....I must be mistaken.
You are thinking of the vent valve solenoid.
Purge valves are usually located under the hood.
Thank you for the correction. I knew there was a valve that I didn't ever want to have to deal with.
That's the trade-in valve.
