5KCSTQ Hot Start Problem...the saga continues

["Kurt Wesseling" <kwessel@enm.maine.edu>]

Mike & all...

More details on my '87 5KCSTQ hotstart problem.  Seems to be very
similar to the one Russ was having and solved, earlier this month.
Still collecting comments. 

To restate the problem, when the car is cold, after sitting all
night, it starts a bit harder than it did before I replaced the fuel
pump 2 weeks ago, but it always starts.  After running the engine up
to temperature, and shutting down, if I then turn the key
immediately, she starts immediately.  I confirmed today that if I
wait as long as 15 minutes and try to restart, there is no problem.

However, if I wait about 60 mins after shutdown she acts like there 
is a fuel starvation problem.  After 6-8 cranks over about a 15 
minute period, she starts with a sputter, then runs perfectly.

I am _fairly_ certain the fuel flow check valve was replaced when the 
pump was replaced.  SO...is this a  fuel system pressure regulator 
problem, metering problem, or what ?

Opinions strongly encouraged....(Phil P., Graydon, etc ..hehheh)
