The first time this happened to me, I disconnected the fuel line 
going into the carb. and there was NO fuel at all.  I then turned
the engine over for a while, and still no fuel from the pump.  I
even went so far as to remove the gas filter, in case it was
blocked, but I still didn't get any fuel when I turned the engine
again.

Ok, my car doesn't suffer from Vapor Lock, it suffers from gasoline
being boiled by hot exhaust pipes creating a buble before the fuel
pump :-).  It's still annoying!  I guess it serves me right for
buying a Dodge.
