Starting Engine After an Extended Shutdown
Before working on a vehicle, set the
parking brakes, place the transmission in
neutral and block the wheels. Failure to
do so can result in unexpected vehicle
movement and can cause serious per-
sonal injury or death.
If an engine has been sitting unused for
more than a week or if an oil change has
been performed, it is recommended that the
oil pressure is established before starting
the engine. This can be done by cranking
the engine without fuel delivered to the
cylinders. Let an experienced technician
carry out the following:
1 Separate the in-line fuse feeding the
engine electronic control unit. The
fuse is located in the battery box.
2 Use the starter to turn the engine over
until the oil pressure registers on the
oil gauge.
CAUTION
Do not crank the engine for more
than 30 seconds at a time; wait two
minutes after each try to allow the
starter to cool. Failure to follow
these instructions could cause
starter damage.
3 Re-connect the fuse.
4 Start the engine.
NOTE! This procedure will load a fault in
the diagnostic message display but will not
interfere with running the engine.
