Car runs fine until I refuel. Afterwards when the ignition is turned the first time seems like the starter sticks until I turn the key off. After that, it will start but I have to pump the accelerator once or twice to get it to start. For a few moments it runs rough, then straightens out and runs fine until the next fill up. My guess is a vacuum issue related with removing the gas cap. Could not locate any loose vacuum hoses. Help would be appreciated.
Evaporative emission
The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test.

Is the check engine light on ? Do you have problems with gas pump shutting off while pumping gas. When the pump shuts off the first time do stop fueling or top off the tank ? Overloading the charcoal canister > Stuck open purge valve .

It could be a loose wire or connector, defective or dirty contacts in
the lock cylinder, broken wire coming from the lock cylinder or a
temperature sensitive module to name a few things.
If this happens only when the temperature is cold, it could be a leaking Fuel Pressure Regulator (FPR), or due to lost pressure in the fuel lines due to cold, in which case you may have to replace the fuel pump / fuel filter / clean injectors.
The best way to diagnose this is to actually take it to a mechanic and have him check for you.
Hope that helps! Should you have any further questions,

That's what was finally found by our Cadillac dealer as well. They charged us too much, though.
SOURCE: Trouble starting only after refueling
same problem 06 CTS...you probably hear a ticking noise under the hood, and car will not start after re-fueling- check engine code is like a p0442? which is a leak in the fuel system. you can try buying a new gas cap from cadillac or an ac-delco distributor to start. its only about twenty dollars. disconnect battery for about ten minutes to reset check engine light or find a local shop with an obd-2 scanner to reset light and re-diagnose. If check engine light comes back on with same code replace the evap. purge valve.(about $25) it is located on the passenger side of car on the intake manifold. it has one electrical connector and two hoses connected to it. no tools required to change which is a plus! disconnect battery or find local shop to reset light again. this should take care of the problem!!
