Note: If the symptom only occurs under certain operating conditions (high idle, full load, engine operating temperature, etc), test the engine under those conditions. Troubleshooting the symptom under other conditions can give misleading results.Diagnostic Codes and Event Codes
Certain diagnostic codes and/or event codes may prevent the engine from starting. Connect the Caterpillar Electronic Technician (ET) and check for active codes and/or for logged codes. Troubleshoot any codes that are present before continuing with this procedure.Electrical Connectors
Check for the correct installation of the J1/P1 and J2/P2 connectors on the Electronic Control Module (ECM). Check for the correct installation of the unit injector connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".Starting Aids
Air Inlet Heater (if equipped)
Ensure that the air inlet heater is programmed to "On". For additional information on the air inlet heater, refer to Troubleshooting, "Air Inlet Heater Circuit - Test".Oil Grade Plugs
Ensure that the correct oil grade plug is installed. For additional information, refer to Operation and Maintenance Manual.Throttle Signal
Monitor the throttle signal on Cat ET. Verify that the throttle signal is stable.

Refer to Troubleshooting, "Throttle Position Sensor Circuit - Test".Injection Actuation Pressure
Ensure that the injection actuation system is operating properly. Refer to Troubleshooting, "Injection Actuation Pressure - Test".Unit Injectors

Refer to Troubleshooting, "Injector Solenoid Circuit - Test" for additional information.Perform the "Cylinder Cutout Test" on Cat ET in order to identify any misfiring cylinder(s). Refer to Troubleshooting, "Injector Solenoid Circuit - Test" for more information.Fuel Supply
Visually check the fuel level. Do not rely on the fuel gauge only. If necessary, add fuel. If the engine has been run out of fuel, it will be necessary to prime the fuel system. Refer to Operation and Maintenance Manual for the correct procedure.
Check the fuel lines for the following problems: restrictions, collapsed lines and pinched lines. If problems are found with the fuel lines, repair the lines and/or replace the lines.
Check the fuel tank for foreign objects which may block the fuel supply.
Prime the fuel supply if any of the following procedures have been performed:
Replacement of the fuel filters
Service on the low pressure fuel supply circuit
Replacement of unit injectorsNote: A sight glass in the low pressure supply line is helpful in diagnosing air in the fuel. Refer to Testing and Adjusting for more information.
Check the fuel filters.
Cold weather adversely affects the characteristics of the fuel. Refer to the Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold weather operation.
Check the fuel pressure during engine cranking. Check the fuel pressure after the fuel filter. Refer to Systems Operation/Testing and Adjusting for the correct pressure values. If the fuel
