Finally got the problem fixed! Turns out it was the (N80) Purge Valve. The old one failed in the open position and as a result allowed fuel fumes from the carbon canister to flow continusly into the intake manifold. During refueling, the amount of fuel fumes would actually flood the engine. I purchased an new Bosch purge valve from Euro Parts Direct for $45. Great price, dealer wanted $138. Installed the new valve, went and refueled the car, and it started right up! So glad to have this one filed away!
