2012 LS hard starting

[wr_guy]

Just got it back from the dealer who could not track down a coolant or oil leak.

Now car don't want to start.

35 deg out
cranks fine just won't light.
press gas pedal and it starts but blubbers rich for about 10 seconds before clearing out and running well.
No CEL.

Any ideas?
Car has just over 36k miles ...warranty?

Update

My son leaves his GPS plugged in overnite...is the Sonic's 12v power outlet switched?

It is switched to the key.


Does it run fine other wise? Just has issues starting?

Yes,

It cranks okay, just won't start unless you give it gas then misfires a while.
After 30sec it runs fine after it cleans out.
Battery is 3 yrs old and the car is used regularly.

I measured 12.3 v on the battery this morning and it started fine for me!
I am going to load test the battery.
Maybe it is not cranking as well as I think?

Maybe there is a bad connection on the battery cables.

I'm gonna clean them.

Any other ideas?

If the starter spins the engine properly there is no battery or battery terminal problem.
