Your
Diesel Engine Won’t Start
If you’ve run
out
of fuel, look at “Running Out of
Fuel”
(see “Diesel
Fuel
Requirements and Fuel System”
in
the
Index).
If you’re
not
out of fuel, and your engine won’t start,
do
this:
Turn your ignition
key
to
RUN.
Make sure that the
GLOW
PLUGS
light is
out. Then IMMEDIATELY
turn
the ignition key to START.
If the light doesn’t go off, wait a few seconds, then try starting your engine
again. And, see your dealer
as
soon
as
you
can for
a
starting system check.
If the light comes
on
and then goes off and
you
know your batteries are
charged, but your engine still
won’t
start,
your
vehicle needs service.
If the light does
not
come on when the engine is cold, your vehicle needs
service.
If
your batteries don’t have enough charge to start your engine, see
“Battery”
in
the Index.
Be sure you have the right oil for your engine, and that you’ve changed
the
oil at the proper times.
If
you use the wrong
oil,
your engine may be harder
to
start.
If
the engine starts, runs a short time, then stops, your vehicle needs service.
