Starting the Engine
The Electronic Control Module (ECM) will automatically provide the correct amount of fuel that is necessary to start the engine. The throttle should not be held while the engine is being cranked. If the engine fails to start in 30 seconds, the starter switch should be released. The starting motor should be allowed to cool for 2 minutes before being used again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
The ECM will set the cold start strategy when the coolant temperature is below 18 °C (64 °F).When the cold start strategy is activated, low idle rpm will be increased to 1000 rpm and engine power will be limited.Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 18 °C (64 °F).
The engine has been running for 14 minutes.Cold mode operation varies the fuel injection amount for white smoke cleanup. Cold mode operation also varies the timing for white smoke cleanup. The engine operating temperature is reached before the walk-around inspection is completed. The engine will idle at the programmed low idle rpm in order to be put in gear.After the cold mode is completed, the engine should be operated at low rpm until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low rpm and low-power demand.
