Diagnostic Codes
Check for any event and active diagnostic codes on the electronic service tool. Troubleshoot any active codes before continuing with this procedure.Electrical Connectors
Check for correct installation of ECM connectors at the following locations:
P1 ECM connector
P2 ECM connector
P100 Engine coolant temperature sensor connector
P201 Engine oil pressure sensor connector
P401 Primary speed/timing sensor connector
P402 Secondary speed/timing sensor connector
P532 Fuel injection pump solenoid connector
Refer to Troubleshooting, "Electrical Connectors - Inspect".
Use the electronic service tool to check for the following logged diagnostic code: 253-02 "Personality Module Mismatch". If this diagnostic code is logged, proceed to Systems Operation, Testing and Adjusting, "Charging System - Test".
Inspect the battery wires from the ECM to the battery compartment. Refer to the Schematic Diagram. Inspect the wires and the power relay. Check the power and ground connections to the ECM. Refer to the schematic diagram for more information.
Repair any faults and ensure that the symptom has been cleared. If the symptom is still present, refer to "Fuel Supply". Fuel Supply
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.
Visually check the fuel tank for fuel. The fuel gauge may be faulty.
Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
Check the primary filter/water separator for water in the fuel.
Check for fuel supply lines that are restricted.
Check that the low pressure fuel lines are tight and secured properly.
Check the fuel filters.
Check the diesel fuel for contamination. Refer to Systems Operation, Testing and Adjusting, "Fuel Quality - Test".
Check for air in the fuel system. Refer to Systems Operation, Testing and Adjusting, "Air in Fuel - Test".
Ensure that the fuel system has been primed. Refer to Systems Operation, Testing and Adjusting, "Fuel System - Prime".
Check the fuel pressure. Refer to Systems Operation, Testing and Adjusting, "Fuel System Pressure - Test".
