Bad purge solenoid. It is in the engine compartment near the intake
manifold and allows the engine to draw off the collected vapors from the
charcoal canister. When they stick open the action of filling the gas
tank drives the vapor up into the intake manifold and you end up with
such a rich mixture that the engine won't start. Very common failure and
symptom.
