long starts fuel pump check valve

[Livolsi, Stephane]

Or it could be something different altogether.  In my actual experience
I was having a hot start problem which gradually became a cold start
problem as well.  In order to 'test' to see if my fuel system was
leaking down, I hot wired my fuel pump so that I could turn it on
independently of the ignition switch (once the car was running, I would
turn the switch off so the safety features were still active)  but this
allowed me to run the fuel pump for 1, 2, 5, 10, 15 minutes before
trying to start.  If the prob was my check valve, then one would expect
that having the fuel pump running for a few minutes before starting
should fix the problem.  The net result for me was nil.  Running the
fuel pump to pressurize the system prior to starting did not help.  I
also checked the other end for wet cylinders and they were dry as a
bone.  The only way to get the car going was to hotwire the cold start
valve to inject some fuel that way, and after it was running (roughly),
then the fuel would start to flow to the injectors.  This leads me to
believe the prob is the fuel distributor and I just haven't had enough
time to learn about it so that I can feel comfortable tackling it.
