Subject: [Amel Yacht Owners] Onan Cranks But Won't Start

 Hi All: My boat, SM
#335, has an Onan 7MDKAL-431 Spec B, 7 kW genset.  It has
2,300 hrs on it and it has been basically flawless with
normal matinenance.  6 months ago I changed the oil, it
operated fine and we put it on the hard in Puerto Rico for
the hurricane season.  Now, having splashed yesterday, I
can't get the darn thing to start.  It cranks, attempts
to start but will not sustain combustion.  Inspection of
the water pump reveals all impeller blades intact (new
impeller), no missing blades to account for since last
change.  The oil level is good, oil is clean.  It seems to
crank a bit slow, so I took the starter off, cleaned up the
brushes and commutator and re-installed it cleaning up all
the terminals as I went.  Still cranks seemingly slow, but
realy plenty fast to start if somehting else wasn;t wrong. 
I changed the fuel filter and bled the system.  I checked
all the sensors (mine doesn't have the fault flashing
light sytem).  I installed my new spare electric fuel pump
(what a pain in the a..), the engineer that designed that
location should be keel-hauled.  I'm kind of running
out of ideas.  Browsed the forum back a year or two and
didn't come up with this scenario or additional ideas. 
Any additional thoughts? Appreciate the
help.   Gary Silver,  Amel SM #335
