Jeep Wrangler: STARTING THE ENGINE — GASOLINE ENGINE (IF EQUIPPED) / If Engine Fails To Start
If the engine fails to start after you have followed the “Normal Starting” or “Extreme Cold Weather” procedure, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there. Crank the engine for no more than 15 seconds. This should clear any excess fuel in case the engine is flooded. Leave the ignition in the RUN position, release the accelerator pedal and 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 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 Ú page 368.
CAUTION!
To prevent damage to the starter, do not continuously crank the engine for more than 25 seconds at a time. Wait 60 seconds before trying again.
Extreme Cold Weather (Below –22°F Or −30°C)
To ensure reliable starting at these
temperatures, use of an externally powered
electric engine block heater (available from an
authorized dealer) is recommended...
