Check for active diagnostic codes on AVSpare Electronic Technician (ET). Troubleshoot any active codes before continuing with this procedure.
- 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 purge the air from the fuel system. Refer to the Operation and Maintenance Manual.
- Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
- Check the fuel lines for the following problems: restrictions, collapsed lines, pinched lines and loose connections. If problems are found with the fuel lines, repair the lines and/or replace the lines.
- Prime the fuel system 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 injectors
Note: A sight glass in the low pressure supply line is helpful in diagnosing air in the fuel. Refer to Systems Operation/Testing and Adjusting.
- Replacement of the fuel filters
- Check the fuel tank for foreign objects which may block the fuel supply.
- Check for air in the system.
- Check the transfer pump and the priming pump for proper operation.
- Check the fuel filters.
- Check the diesel fuel for contamination. Refer to Systems Operation/Testing and Adjusting.
- 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 for a restriction in the air inlet system. If equipped, verify that the air shutoff valves are completely open.
Check the parameter for the low engine idle (if applicable). Refer to Troubleshooting, "Configuration Parameters".
Check all accessory equipment for problems that may create excessive load on the engine. Repair any damaged components or replace any damaged components.
- Perform the "Injector Solenoid Test" on Cat ET in order to determine if all of the injector solenoids are being energized by the ECM.
- Perform the "Cylinder Cutout Test" on Cat ET in order to identify any injectors that might be misfiring.
- If Cat ET indicates a problem, remove the electronic unit injector from the suspect cylinder and install a new electronic unit injector. Refer to Disassembly and Assembly.
- Ensure that the repairs have eliminated the problem. If there is still a problem, refer to the circuit test Troubleshooting, "Injector Solenoid - Test".
