If Engine Fails To Start
WARNING!
•
Never pour fuel or other flammable liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal injury.
•
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle. If the vehicle has a discharged
battery, booster cables may be used to
obtain a start from a booster battery or the
battery in another vehicle. This type of start
can be dangerous if done improperly. Refer
to “Jump Starting” in “What to Do In Emer-
gencies” for further information.
Without Tip Start
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. Push
the accelerator pedal all the way to the floor
and hold it there while cranking the engine. This
should clear any excess fuel in case the engine
is flooded.
CAUTION!
To prevent damage to the starter, do not crank
the engine for more than 15 seconds at a
time. Wait 10 to 15 seconds before trying
again.
If the engine is flooded, it may start to run, but
not have enough power to continue running
when the key is released. If this occurs, con-
tinue cranking up to 15 seconds with the ac-
celerator pedal pushed all the way to the floor.
Release the accelerator pedal and the key
once the engine is running smoothly.
If the engine shows no sign of starting after two
15 second periods of cranking with the accel-
erator pedal held to the floor, repeat the “Nor-
mal Starting” or “Extreme Cold Weather” pro-
cedures.
With Tip Start
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold
Weather” procedures, it may be flooded. To
clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it. Then,
turn the ignition switch to the START position
and release it as soon as the starter engages.
The starter motor will disengage automatically
in 10 seconds. Once this occurs, release the
accelerator pedal, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
