164 warm engine hard start

[Ferdinando Di Matteo <ferdinando.di@xxxxxxxx>]

Why do I think the problem is not with fuel pressure at the injectors or
why it cannot be the fuel pump check valve or short hose?  Because if that
were so, it would not have fuel at the rail when cold.  Since there is no
cold-start injector, the enriched mixture signal comes from the brain and
all injectors open to enrich.  If it is necessary to open the hrottle some,
then the idle air unit is not opening enough, you still should not open the
throttle to start.  Fred Di Matteo, AROC Technical Advisor.
