Need Help With Check Engine Light
I recieved the check engine light. My friend hooked up his OBD-II and scanned the code PO455 Evaporative Emissions Control Fault - Major leak. I traced it down to the fuel cap. He re-set the light. Now I'm wondering if something is wrong now since the light does not even come on, Not even when the car first starts. Is it possible that I did something wrong. The OBD manaul said to turn on the ignition. I did start the car with the OBD connected because I did not know how to just turn on the ignition with a push button start. The OBD would not scan in the Accessory mode. Any help, thoughts or comments would be appreciated.
Thanks in Advance.

Had similar.. Although, I used OnStar. They had me reseat the gas cap. They suggested bad gas. It was and I have not had a Check Engine light since.
Oops, forgot to mention that I only use Amoco Ultimate - from a new service station.
In the problem above - I filled up at an old station in the sticks....'Nuff said

Oh, BTW, you didn't do anything wrong. It is Ok to scan the car with the engine running.
