no start

[Phil Rose]

Speaking of "no start" problems. I (and others) have posted about the
common "hot re-start" problem, which most people agree is caused by
some internal leakdown which allows the the fuel lines to
depressurize--usually involving the fuel-pump check valve.  I still
have a question--pertaining to our car-- that may (or not) be
relevant to understanding the cause of this problem.

Question: Why is it that when the first attempt at hot restart fails,
the car invariably starts quickly on the 2nd attempt--no matter how
long (or short!!!) the initial cranking period was? In other words,
if we crank the engine and there's no rapid startup (say within 2 or
3 seconds), then it's likely that we'd have to keep cranking for
10-15 seconds before the engine fires. However if we stop the first
try after a just few seconds, the 2nd try will catch very quickly.
Or so it seems.
