John,
 
If you can hear each injector click, = then it is unlikely that one of them is hanging.  This is particularly= likely if the sound has a slight ring to it.  A questionable inj= ector may sound like more of a dull thump.
 
I second Kelly's suggestion.  If= you haven't already done this, can you shut off the fuel supply to the car= burator with the injectors disabled and wait until the engine dies of fuel = starvation?  Then try starting the engine with the fuel supply only enabled to the injectors and not the carburator.=

John,
    This may be a stretch but could you be pulling resi= dual fuel from the Weber float bowl when starting on the injectors cau= sing the flooding ??.............
