1.
1. Using the Scan tool, check for DTCs. Troubleshoot any active DTCs beforeperforming this test.
2. Disconnect the wiring harness from the lift pump at the fuel tank module connector and inspect the pins for
damage. Fix or replace any damaged component.
3. Connect a voltmeter between the fuel lift pump supply and return pins at the fuel tank module connector.
4. Turn the ignition to the on position. Use the Scan tool to actuate the fuellift pump, record the voltage on the
voltmeter.
5. If the voltage is greater than 11.5 volts, go to step 14. If the voltage is lessthan11.5volts,gotostep6
6. Using a voltmeter, measure the battery voltage to determine that the voltage is greater than 11.5 volts. If the
voltage is greater than 11.5 volts, go to step 7. If the voltage is not greater than 11.5 volts, troubleshoot for low
battery voltage.
7. Remove the fuel lift pump relay from the PDC. Use a voltmeter to measure the voltage at the fuel lift pump relay
voltage supply pin in the PDC. If the voltage is greater than 11.5 volts, go to step 8. If the voltage is not greater than
11.5 volts, fix or replace the harness.
8. Remove the fuel lift pump relay from the PDC. Install a spare relay in place of the fuel lift pump relay. Using the
Scan tool, actuate the fuel lift pump. Use a voltmeter to measure the voltage between the fuel lift pump supply and
return pins at the fuel tank module connector while the fuel lift pump is actuated. If the voltage is greater than 11.5
volts, replace the fuel lift pump relay. If the voltage is not greater than 11.5volts,gotostep9.
9. Disconnect the wiring harness from the fuel tank module. Remove the liftpump relay from the PDC. Using an
Ohmmeter, measure the resistance of the fuel lift pump power supply wire between the PDC relay output pin and
the fuel tank module connector. If the resistance is less than 10 ohms, go tostep 10. If it is greater than 10 ohms,
fix or replace the harness.
10. Disconnect the wiring harness from the fuel tank module. Remove the fuel lift pump relay from the PDC. Using
a voltmeter, measure the voltage between battery negative and the fuel lift pump power supply wire at the fuel
module connector. If the voltage is less than 1 volt, go to step 11. If the voltage is greater than 1 volt, fix or replace
the harness.
11. Disconnect the wiring harness from the fuel tank module. Remove the fuel lift pump relay from the PDC. Using
an ohmmeter, measure the resistance between battery negative and the fuellift pump power supply wire at the fuel
module connector. If the resistance is less than 10 ohms, fix or replace theharness. If the resistance is greater than
10 ohms, go to step 12.
12. Disconnect the wiring harness from the fuel tank module. Using an Ohmmeter, measure the resistance of the
fuel lift pump ground wire between the fuel tank module connector and battery negative. If the resistance is less
than 10 ohms, go to step 13. If the resistance is greater than 10 ohms, fix or replace the harness.
13. Disconnect the wiring harness from the fuel tank module. Using a voltmeter, measure the voltage between the
fuel lift pump ground wire and battery negative. If the voltage is less than1 volt, go to step 14. If the voltage is
greater than 1 volt, fix or replace the harness.
14. Reconnect the lift pump connector.
FLOW TEST.
1. Remove the fuel pump supply banjo fitting from the fuel injection pump.
2. Install Miller Tool #9014 fuel system test fitting into the fuel injection pump.
3. Connect one end of a section of fuel hose to the test fitting.
4. Put the other end of the fuel hose into an empty fuel container.
5. Use the scan tool to actuate the fuel lift pump.
6. While the lift pump is running, move the fuel hose from the fuel canister into a 1000ml graduated cylinder for 10
seconds.
7. Read and record the amount of fuel in the graduated cylinder after 10 seconds.
8. If you have more than 430ml in the graduated cylinder after 10 seconds, the test has successfully passed.
9. If you have less than 430ml of fuel in the graduated cylinder, inspect thefuel supply line from the fuel tank to the
fuel filter housing and the fuel supply line between the fuel filter housing and the high pressure fuel pump for signs
of damage, replace as necessary. If no damage is found, replace the fuel filter and retest.
10.Verify the Screened Banjo Bolt at the outlet of the fuel filter is free ofdebris. If debris is found, rinse screen with
water, blow dry and reinstall. Retest vehicle. If flow meets specification then trace back the source of debris, if flow
is still below spec repair damaged component.

Diagnostic Test
1.INTERMITTENT CONDITION
NOTE: The conditions that set the DTC are not present at this time. The following list may help in identi-
fying the intermittent condition.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands
near the pulleys, belts, or fan. Do notwear loose clothing. Failure to follow these instructions can result in
personal injury or death.
Refer to any Technical Service Bulletins (TSBs) that may apply.
Review the scan tool Freeze Frame information. If possible, try to duplicate the conditions under which the DTC set.
With the engine running at normal operating temperature, monitor the scantool parameters relatedtotheDTCwhile
wiggling the wire harness. Look for parameter values to change and/or a DTCto set.
Turn the ignition off.
Visually inspect the related wire harness. Disconnect all the related harness connectors. Look for any chafed,
pierced, pinched, partially broken wires and broken, bent, pushed out, orcorroded terminals.
Perform a voltage drop test on the related circuits between the suspected faulty component and the PCM.
Inspect and clean all PCM, engine, and chassis grounds that are related to the most current DTC.
If numerous trouble codes were set, use a wire schematic and look for any common ground or supply circuits.
For any Relay DTCs, actuate the Relay with the scan tool and wiggle the related wire harness to try to interrupt the
actuation.
For intermittent Evaporative Emission trouble codes perform a visual andphysical inspection of the related parts
including hoses and the Fuel Filler cap.
For intermittent Misfire DTC’s check for restrictions in the Intake and Exhaust system, proper installation of Sensors,
vacuum leaks, and binding components that are run by the accessory drive belt.
Use the scan tool to perform a System Test if one applies to failing component.
A co-pilot, data recorder, and/or lab scope should be used to help diagnoseintermittent conditions.
