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.
Diagnostic Codes
Use one of the following methods to check for active diagnostic codes:
The electronic service tool
The display on the control panel
Flash CodesElectronic Service Tool
Connect the electronic service tool to the diagnostic connector.
Check for active diagnostic codes on the electronic service tool.
Investigate any active codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code". Display on the Control PanelNote: The following procedure is only applicable if the application is equipped with a display on the control panel.
Check the display on the control panel for active diagnostic codes.
Troubleshoot any active codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code". Flash CodesNote: The following procedure is only applicable if the machine is equipped with the appropriate warning lamps.
Check the warning lamps on the control panel for flash codes. Flash codes are explained in Troubleshooting, "Flash Codes".
If any flash codes are displayed, troubleshoot the codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code". Electrical Connectors
Refer to Troubleshooting, "Electrical Connectors - Inspect".
Repair the electrical connectors or replace the electrical connectors.
Ensure that all the connector seals are in place and that the connectors have been correctly installed.
Ensure that the repairs have eliminated the fault. If the fault has not been eliminated proceed to "ECM Connection". ECM Connection
Check that the P2/J2 connector is correctly fitted.
Check that the P1/J1 connector is correctly fitted.
If a fault is suspected with the ECM power and ground connections, refer to Troubleshooting, "Ignition Keyswitch Circuit and Battery Supply Circuit - Test".
Verify that the ECM connections for the power and ground connections at the fuel pump are correctly connected.
Repair any faults and ensure that the faults have been eliminated.
If the repairs do not eliminate the faults, proceed to "Fuel Supply". Fuel Supply
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 that the Electric Fuel Lift Pump (EFLP) is operating. If the EFLP is suspect, refer to Troubleshooting, "Fuel Pump Relay Circuit - Test".
Replace the in-line fuel strainer that is upstream of the primary fuel filter.
Replace the primary and secondary 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. Start the engine and then use the electronic service tool to check that the pressure in the fuel rail is more than 18000 kPa (2610 psi).
If the fault has not been eliminated, perform the following procedure: Note: Before performing the following fuel system tests, the engine must be run for a minimum of 30 minutes.Note: When performing the following fuel system tests, the Electric Fuel Lift Pump (EFLP) will only operate for 2 minutes unless the engine is running. If necessary, cycle the keyswitch in order to reactivate the pump.

(1) Return line pressure relief valve
(2) Secondary fuel filter base
(3) Transfer pump inlet regulator (TPIR)
(4) Transfer pump inlet regulator return port Transfer Pump Inlet Regulator (TPIR) Flow Test
Refer to Illustration 1.Perform the following procedure:
Make sure the keyswitch is in the OFF position.
Disconnect the TPIR return line from the drain port on the TPIR. Install a suitable blanking cap on the open port in the TPIR return line
Connect a temporary drain line to the drain port on the TPIR.
Place the end of the temporary drain line into a suitable calibrated container.
With the keyswitch in the ON position but the engine not running, use a suitable multimeter to measure the input voltage to the EFLP. Record the reading.
With the keyswitch in the ON position but the engine not running, measure the fuel flow from the temporary drain line. For a 12 VDC system, refer to Illustration 2 for the minimum acceptable flow rate. For a 24 VDC system, refer to Illustration 3 for the minimum acceptable flow rate.
Illustration 2 g02355128
Minimum TPIR flow rate for a 12 VDC system
Illustration 3 g02355130
Minimum TPIR flow rate for a 24 VDC system
Remove the temporary drain line from the drain port on the TPIR. Connect the TPIR return line to the TPIR.
If the fuel flow in Step 6 is greater than the minimum limit, proceed to "Intake Manifold Pressure".
If the fuel flow in Step 6 is below the minimum limit, proceed to "Return Line Pressure Relief Valve Test".
If there is no fuel flow in Step 6, proceed to "Transfer Pump Inlet Regulator (TPIR) Return Test". Transfer Pump Inlet Regulator (TPIR) Return Test
In order to check the return flow from the TPIR, perform the following procedure:
Make sure that the TPIR return line is not blocked or kinked.
If the TPIR return line is clear, confirm that the Electric Fuel Lift Pump (EFLP) is operating. Make sure that fuel lines between the EFLP and the TPIR are not blocked or kinked.
If the fuel lines to the TPIR are clear and the EFLP is operating, replace the TPIR.
If the fault is still present, proceed to "Intake Manifold Pressure". Return Line Pressure Relief Valve Test
In order to check the return line pressure relief valve in the secondary fuel filter base, perform the following procedure:
Make sure the keyswitch is in the OFF position.
Disconnect the return line banjo connection on the top of the secondary fuel filter.
Use a suitable blank to plug the return line.
Install a suitable drain line to the return line point on the top of the secondary
