Refer to Operation and Maintenance Manual, "General Hazard Information and High-Pressure Fuel Lines" before adjustments and repairs are performed.Note: Refer to Systems Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.Ensure that all adjustments and repairs are performed by authorized personnel that have had the correct training.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
If air enters the fuel system, the air must be purged from the fuel system before the engine can be started. Air can enter the fuel system when the following events occur:
The fuel tank is empty or the fuel tank has been partially drained.
The low-pressure fuel lines are disconnected.
A leak exists in the low-pressure fuel system.
The fuel filter has been replaced.
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.
The fuel system should be primed after a unit injector is changed or when the fuel system is dry.Note: The fuel system does not require priming when the primary fuel filters or secondary fuel filters are changed or when an Electronic Control Module (ECM) is replaced. When the engine is started under these circumstances, the engine may momentarily run rough until the air is purged from the system.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over any disconnected fuel system components.
Follow the procedure below to prime the engine with fuel.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Electric Fuel Priming Pump
Ensure that the fuel system is in working order. Restore the fuel supply.
The electric fuel priming pump will operate for 90 seconds. If necessary the electric fuel priming pump can be stopped during the 90 seconds of operation, by operation of the switch.
Turn the keyswitch to the "RUN" position. Operate the switch for the electric priming pump. After 100 seconds of the electric fuel priming pump operation, the fuel system will be primed and the electric fuel priming pump will turn off.
The engine should now be able to start.Note: Do not loosen the high-pressure fuel line to purge air from the fuel system. This procedure is not required.
Operate the engine starter and crank the engine. After the engine has started, operate the engine at low idle for a minimum of 5 minutes. Operate engine immediately after air has been removed from the fuel system.Note: Operating the engine for this time will help ensure that the fuel system is free of air.After the engine has stopped, wait for 10 minutes to allow the fuel pressure to be purged from the high-pressure fuel lines before any service or repair is performed on the engine fuel lines. If necessary, perform minor adjustments. Repair any leaks from the low-pressure fuel system and from the cooling, lubrication, or air systems. Replace any high-pressure fuel line that has leaked. Refer to Disassembly and Assembly, "Fuel Injection Lines - Install".If you inspect the engine in operation, always use the proper inspection procedure to avoid a fluid penetration hazard. Refer to Operation and Maintenance Manual, "General hazard Information".
