Information:


Disconnect the fuel pump.
Turn the keyswitch to the ON position.
Proceed to the "Diagnostic Overrides" screen on Cat ET.
Activate the relay for the fuel pump.Note: The diagnostic override will only activate the relay for 120 seconds.
Use signal reading probes to measure the voltage across terminal 2 (Ground) and terminal 5 (Fuel Pump Power) of the relay.Expected Result:The supply voltage is greater than 22.0 VDC.Results:
OK - The ECM is properly controlling the relay for the fuel pump, but the fuel pump is not working.Repair: Replace the fuel pump.Verify that the repair eliminates the problem.STOP
Not OK - The fuel pump is not receiving the correct signal. Proceed to Test Step 6.Test Step 6. Check the Resistance of the Relay

Relay Terminals
Turn the keyswitch to the OFF/RESET position.
Unplug the relay for the fuel pump.
Measure the resistance between terminal 1 (Fuel Pump Relay (Signal)) and terminal 2 (Ground) of the relay.Expected Result:The resistance is between 250 Ohms and 500 Ohms.Results:
OK - Proceed to Test Step 7.
Not OK - The relay is faulty.Repair: Replace the relay.Verify that the repair eliminates the problem.STOPTest Step 7. Check the Signal Voltage to the Relay

Use signal reading probes to measure the voltage across terminal 2 (Ground) and terminal 5 (Fuel Pump Power) of the relay.Expected Result:The voltage is 24.0 8.0 VDC.Results:
OK - There is a problem in the wiring between the relay and the fuel pump.Repair: Repair the circuit.Verify that the repair eliminates the problem.STOP
Not OK - The relay is not sending power to the fuel pump. Proceed to Test Step 9.Test Step 9. Check the Power Supply to the Relay
Illustration 8 g01116878
Relay Terminals
Unplug the fuel pump.
Measure the voltage between terminal 3 (+Battery) of the connector for the relay and terminal 2 (Ground).Expected Result:The voltage is 24.0 8.0 VDC.Results:
OK - The relay is faulty.Repair: Replace the relay.Verify that the repair eliminates the problem.STOP
Not OK - There is a problem in the wiring between the relay and the +Battery terminal.Repair: Repair the circuit.Verify that the repair eliminates the problem.STOPTest Step 10. Check for Shorts in the
