Electrical connectors
Air intake and exhaust system
Valve lash
Turbocharger (if equipped)
Fuel supply
Low compression (cylinder pressure)Recommended Actions
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.
Note: The procedures have been listed in order of probability. Complete the procedures in order.Note: If the problem only occurs under certain conditions, test the engine under those conditions. Examples of certain conditions are high engine speed, full load, and engine operating temperature. Troubleshooting the symptoms under other conditions can give misleading results.

Troubleshooting Test Steps Values Results
1. Diagnostic Codes
Note: Certain diagnostic codes and/or event codes may cause poor performance. Refer to in the electronic service tool.
A. Use the electronic service tool to check for active or logged codes. Engine Derate or Diagnostic Codes Result: A diagnostic code is present.
Troubleshoot the code and then reset the histogram.
Result: A diagnostic code is not present.
Proceed to Test Step 2.
2. Parameters in the Electronic Control Module (ECM)
A. Use the electronic service tool to verify that the correct engine rating has been provided.
B. Use the electronic service tool to verify the maximum engine speed limit.
C. Ensure that the repairs have restored the expected performance. Parameters Result: The parameters are not correct.
Input the correct parameters. Refer to Troubleshooting, "Customer Specified Parameters" for additional information.
Result: The parameters are correct.
Proceed to Test Step 3.
3. Electrical Connectors
A. Turn the keyswitch to the OFF position.
B. Check the engine harness for abrasions and pinch points.
C. Inspect the terminals on the engine sensor connectors. Refer to Troubleshooting, "Electrical Connector - Inspect".
D. Inspect the terminals on the engine ECM connectors. Refer to Troubleshooting, "Electrical Connector - Inspect". Loose connection or damaged wire Result: There is a fault in a connector or the wiring
Repair any faulty connectors or replace the wiring harness. Ensure that all of the seals are properly in place and ensure that the connectors are correctly coupled.
Result: All connectors, pins, and sockets are correctly coupled and/or inserted. The harness is free of corrosion, abrasion, and pinch points.
Proceed to Test Step 4.
4. Air Intake and Exhaust System
A. Check the air filter restriction indicator, if equipped. Replace a plugged air filters. Refer to the Operation and Maintenance Manual.
B. Check the air inlet and exhaust system for restrictions and/or leaks. Restrictions Result: There are restrictions in the air inlet or exhaust system.
Make the necessary repairs, Refer to Systems Operation/Testing and Adjusting, "Air Inlet and Exhaust System - Inspect" for additional information.
Result: There are no restrictions in the air inlet or exhaust system.
Proceed to Test Step 5.
5. Valve Lash
Note: The valve lash can affect the performance of the engine.
A. Check the valve lash. Refer to Systems Operation, Testing, and Adjusting, "Engine Valve Lash - Inspect". Valve lash Result: The valve lash is not set correctly.
Set the valve lash. Refer to Systems Operation, Testing, and Adjusting, "Engine Valve Lash - Inspect/Adjust" for the correct procedure.
Result: The valve lash is correct.
Proceed to Test Step 6.
