If Your Diesel Engine Will Not Start
If you have run out of fuel, see Running Out of Fuel on
page 5-17.
If you are not out of fuel, and your engine will not start,
do this:
Turn your ignition key to RUN. Immediately after the
wait to start light goes off, turn the ignition key to
START.
If the light does not 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 will not
start, your vehicle needs service.
If the light does not come on when the engine is cold,
your vehicle needs service.
If your batteries do not have enough charge to start
your engine, see Battery on page 5-58.
Be sure you have the right oil for your engine, and that
you have changed the oil at the proper times. If you
use the wrong oil, your engine may be harder to start.
Be sure you are using the proper fuel for existing
weather conditions. See What Fuel to Use on page 5-8.
If the engine starts, runs a short time, then stops,
your vehicle needs service.
CAUTION:
{
Do not use gasoline or starting aids, such as
ether, in the air intake. They could damage
your engine. There could also be a fire, which
could cause serious personal injury.
