If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
•
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion 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
