| SYMPTOM | POSSIBLE CAUSES | ACTION |
|---|---|---|
| Engine cranks, but does not start |
|
Check the fuel level and condition. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the lift pump operation, check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTCs indicating a fuel volume or pressure control valve fault. Check the fuel pump. Check the crankshaft position sensor circuits. Refer to the electrical guides |
| Difficult to start |
|
Check the glow plug circuits. Refer to the electrical guides. Check the fuel level/condition. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the lift pump operation, check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTCs indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system |
| Rough idle |
|
Check the intake air system for leaks. Check the low pressure fuel pump operation.

Check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTCs indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system |
| Lack of power when accelerating |
|
Check the intake air system for leakage or restriction. Check for a blockage/restriction in the exhaust system, install new components as necessary. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Check for DTCs indicating a fuel pressure fault. Check the exhaust gas recirculation system. Check turbocharger actuator |
| Engine stops/stalls |
|

Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the fuel system for leaks/damage: Check for DTCs indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system |
| Engine judders |
|
Check the fuel level/condition. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the low-pressure fuel system for leaks/damage. Check the high pressure fuel system for leaks, check for DTCs indicating a fuel volume or pressure control valve fault. Check the fuel pump |
| Excessive fuel consumption |
|
Check the low-pressure fuel system for leaks/damage. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. Check for DTCs indicating a fuel volume or pressure control valve fault. Check the fuel temperature sensor, fuel pump, etc for leaks. Check for injector DTCs. Check the exhaust gas recirculation system |
