George,

As a novice with fuel injected engines I was and am looking for something 
that works.  I agree that if the fuel pump will not pump fuel you will not get 
the engine started.  And yes if the pump and fuel system is cool you will 
always 
get a normal start.  However,  I do not always want to sit for the hour or 
two that it takes to cool down the fuel system.  Perhaps we need to come up 
with 
a pre-cooler for the engine to start them hot like the pre heater to start 
them cold.  

The vaporizing fuel may not be causing a flooded engine but it appears that a 
"flooded engine" start procedure works for most people.  However the engine 
may not be flooded. 

When it comes to fuel pumps I believe the engine driven diaphragm pump will 
always pump fuel.  Liquid or vapor it will pump.  If it is pumping vapor the 
injection system will not be able to meter it properly.  It will probably be 
lean rather than rich, but if it pumps enough it will eventually bring in 
cooler 
fuel and raise the pressure and reduce vaporization.  Once you have pressure 
the fuel will stay liquid and you get a start.  So yes the key is the fuel 
pump.  In my case my boost pump is a Dukes centrifugal and it will not pump 
vapor. 
  It would be not help in hot starts  

So the bottom line is how do you get consistent starts with a hot engine.  In 
my case it is a normal start without boost pump prime.  Crank until it fires 
and richer the mixture.  It probably starts because it cranked enough to bring 
in enough cool fuel to stay liquid in the pump and raise the fuel pressure.  
But for what ever reason so far it works consistently.  

Again thanks for the input.  It makes all our braincells work a little bit.
