Mike,

Why did you disconnect the blue cold start valve? My understanding on 
this is that the hot start problem is that the accumulator doesn't hold the 
rest pressure in the fuel lines so when you go to start the car when its hot, 
theres no pressure in the lines. It has nothing to do with the cold start 
valve. Maybe what you misunderstood is what everyone else is talking about 
with the cold start valve and removing the plug to it. In the engine 
compartment, the control pressure regulator gets a constant power when the 
ignition is on, so if you are having a hot start problem, the sensor that 
would normally turn on the cold start valve is disabled because its hot and 
by switching the plugs for the cold start valve and the control pressure 
regulator you are powering up the cold start valve and sending fuel to the 
engine to make it start hot. I would connect that cold start valve up again 
if I were you.

Later,
Nick
