THE PURGE SOLANOID IS ON THE ENGINE WITH A RED CONNECTOR ON IT. IT IS LOCATED ON THE REAR OF THE ENGINE ABOVE THE REAR VALVECOVER. YOU ARE ACTUALLY LOOKING FOR THE CANISTER VENT SOLANOID AND IT IS IN THE REAR OF THE CAR AND THEY FAIL OFTEN. GET THE PART FROM G.M. AND THEY CAN TELL YOU EXACTLY WHERE IT IS. THE G.M. PART IS UNDER $30.00.

You will need to remove the right front wheel & wheel well liner. The canister purge valve is behind the cover. It should have two tube going into the bottom and one on the side near the top.
You can fix it!
If this helps you out please rate me!

in my experience the usual culprit is the evap cannister. the problem is it gets moisture in it and freezes during winter thus cracking the plastic. if you lay under the car and look at the evap box it black plastic and if you see a loose or cracked hose or the box itself is cracked that is most likely it. as a side note you can check the gas cap and buy a new one to see if that rectifies the situation. lastly i don't think the gas tank should be suspect as you would probably notice if gas was leaking out of the tank. if you take the car to a dealer or shop they can do a smoke test and determine where the leak is.
