Troubleshooting Test Steps Values Results
2. Check the Starting Priority Valve
A. Turn the keyswitch to OFF.
B. Remove the starting priority valve from the secondary fuel filter head. Refer to the Disassembly and Assembly manual for proper procedure.
C. Check the starting priority valve operation by actuating the spool within the cartridge assembly.
Starting Priority Valve
Result: The starting priority valve is OK.
Reinstall the starting priority valve.
Proceed to Test Step 3.
Result: The starting priority valve is NOT OK.
Repair: Replace the starting priority valve.
Proceed to Test Step 8.
3. Check the Low-Pressure Fuel System Pressure Regulator
A. Turn the keyswitch to OFF.
B. Remove the low-pressure fuel system pressure regulator from the secondary fuel filter auxiliary manifold. Refer to the Disassembly and Assembly manual for proper procedure.
C. Check the low-pressure fuel system pressure regulator by actuating the spool within the cartridge assembly.
Low-Pressure Fuel System Pressure Regulator
Result: The low-pressure fuel system pressure regulator is OK.
Repair: Reinstall the low-pressure fuel system pressure regulator.
Proceed to Test Step 4.
Result: The low-pressure fuel system pressure regulator is NOT OK.
Repair: Replace the low-pressure fuel system pressure regulator.
Proceed to Test Step 8.
4. Check the Injector Cooling Supply Orifice
A. Turn the keyswitch to OFF.
B. Disconnect the injector cooling supply line from the secondary fuel filter head.
C. Remove the orifice from the secondary fuel filter head. Refer to the Disassembly and Assembly manual for proper procedure.
D. Inspect the injector cooling supply orifice.
Blockage
Result: The injector cooling supply orifice was OK.
Repair: Reinstall the injector cooling supply orifice.
Proceed to Test Step 5.
Result: The injector cooling supply orifice was NOT OK.
Repair: Clean the blockage from the injector cooling supply orifice.
Proceed to Test Step 7.

Troubleshooting Test Steps Values Results
5. Check the Injector Back-pressure Regulator
A. Turn the keyswitch to OFF.
B. Remove Injector back-pressure regulator from the low-pressure injector cooling manifold in the fuel cooling rail. Refer to the Disassembly and Assembly manual for the proper procedure.
C. Check the Injector back-pressure regulator by actuating the spool within the cartridge assembly.
Injector Back-pressure Regulator
Result: The injector back-pressure regulator is OK.
Repair: Reinstall the injector back-pressure regulator.
Proceed to Test Step 6.
Result: The injector back-pressure regulator is NOT OK.
Repair: Replace the injector back-pressure regulator.
Proceed to Test Step 7.
6. Check the Fuel Cooler (If Equipped)
A. Turn the keyswitch to OFF.
B. Install a pressure gauge in the fuel return line between the high-pressure fuel return line and the customer connection to the fuel cooler and fuel tank.
C. Start the engine and operate at high idle.
Restriction
Result: The pressure was less than 50 kPa (7.3 psi).
Proceed to Test Step 7.
Result: The pressure was greater than 50 kPa (7.3 psi). A restricted fuel cooler has been detected.
Repair: Replace the fuel cooler.
Proceed to Test Step 7.
7. Check for Codes
A. Start the engine and operate at high idle for 1 minute.
B. Look for active or logged diagnostic codes.
Codes
Result: No codes present.
Return to service.
