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.Electric Fuel Priming Pump
Use the following procedure to remove air from the fuel system:
Ensure that the fuel system is in working order. Check that the fuel supply valve (if equipped) is in the "ON" position.
Turn the keyswitch to the "RUN" position.
The keyswitch will allow the electric priming pump to operate. Operate the electric priming pump. The ECM will stop the pump after 2 minutes.
Turn the keyswitch to the "OFF" position. The fuel system should now be primed and the engine should be able to start.
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. Ensure that the fuel system is free from leaks.Note: Operating the engine for this period will help ensure that the fuel system is free of air.DO NOT loosen the high-pressure fuel lines to purge air from the fuel system. This procedure is not required.After the engine has stopped, you must 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. The 10 minute wait will also allow static charge to dissipate from the low-pressure fuel system. 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 Manual, "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".If the engine will not start, refer to Troubleshooting, "Engine Cranks but will not Start".Mechanical Fuel Priming Pump
Use the following procedure to remove air from the fuel system:
Ensure that the fuel system is in working order. Check that the fuel supply valve (if equipped) is in the "ON" position.
Operate the hand priming pump. Count the number of operations of the pump. After approximately 80 depression of the pump stop.Note: As the fuel system is primed, the pressure will increase within the fuel system and this increase in pressure can be felt during priming.
The fuel system should now be primed and the engine should be able to start.
Operate the engine starting motor and crank the engine. After the engine has started, operate the engine at low idle for a minimum of 5 minutes. Ensure that the fuel system is free from leaks.Note: Operating the engine for this period will help ensure that the fuel system is free of air.DO NOT loosen the high-pressure fuel lines to purge air from the fuel system.
