'885KCSTQ Long cranking above 75 F ambient temp

[benswann at comcast.net]

Lou,

I have spent too much time in the past to determine if this is the culprit.  If
you have the time to pull your injectors twice to verify weepage and then do
the actual replacement later, have at it. I fell for this not believing other
lister's experience.  Never again - I think collective experience dictates to
order new Viton tipped injectors with new seals and just replace them.  This
will run you under $50 and injector and you may be able to get them for as low
as $35 ea.

There are other things that can cause these symptoms - one being the fuel
pressure accumulator, but do your injectors first and if problem persists or is
not completely resolved then look elsewhere.

I have had a number of 5ktqs with over 130 kmi that had the long cranking
problem.  Replacement of injectors brough cranking from 7-10 sec to under 2
sec. consistantly.  Any other repairs such as fuel pressure accum. were icing
on the cake.
