Once the intake is full of this fuel vapor mixture the engine doesn't want to start as the mixture is all messed up.

Do you mean the valve
under the driver's-side intake manifold? After spending four days reading up on the EVAP system, that's the valve I zeroed in on. Several people whose 986 had the same symptom as mine fixed the problem by replacing that valve. What's somewhat confusing is the nomenclature folks use to refer to it: purge valve, purge solenoid, fuel vent valve, fuel system vapor valve, tank vent valve, etc. Hard to be sure they're talking about the same valve. My next move is to give Pelican a call, describe the problem, and see if I'm on the right track. And find out the valve's official name.
