ACTION
APPLICABILITY
1
Turn the ignition on.
With the DRBIII
t, actuate the ASD Fuel System test.
Note: It may be necessary to use a mechanics stethoscope in the next step.
Listen for fuel pump operation at the fuel tank.
Does the Fuel Pump operate?
All
Yes
→ Go To 2
No
→ Go To 5
Caution: Stop All Actuations.
2
Turn the ignition off.
WARNING: The fuel system is under a constant pressure even with the
engine off. Before testing or servicing any fuel system hose, fitting or line,
the fuel system pressure must be released.
Install a fuel gauge.
Turn the ignition on.
With the DRBIII
t, actuate the ASD Fuel System test and observe the fuel pressure
gauge.
NOTE: Fuel pressure specification is 400 KPa +/- 34 KPa (58 psi +/- 5 psi).
Choose a conclusion that best matches your fuel pressure reading.
All
Below Specification
Within Specification
The Fuel Delivery System is operating normally.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
Above Specification
Replace the fuel filter/fuel pressure regulator.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
Caution: Stop All Actuations.

3
Turn the ignition off.
WARNING: The fuel system is under a constant pressure even with the
engine off. Before testing or servicing any fuel system hose, fitting or line,
the fuel system pressure must be released.
Raise vehicle on hoist, and disconnect the fuel pressure line at the fuel pump module.
Install special 5/16 fuel line adapter tool #6539 between the disconnected fuel line
and the fuel pump module.
Attach a fuel pressure test gauge to the T fitting on the tool #6539
Turn the ignition on.
With the DRBIII
t, actuate the ASD Fuel System test and observe the fuel pressure
gauge.
NOTE: Fuel pressure specification is 400 KPa +/- 34 KPa (58 psi +/- 5 psi).
Is the fuel pressure within specification now?
All
Yes
→ Repair/replace fuel supply line as necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Go To 4
Caution: Stop All Actuations.
4
Turn the ignition off.
WARNING: The fuel system is under a constant pressure even with the
engine off. Before testing or servicing any fuel system hose,fitting or line,
the fuel system pressure must be released.
Remove the Fuel Pump Module and inspect the Fuel Inlet Strainer.
Is the Fuel Inlet Strainer plugged?
All
Yes
→ Replace the Fuel Pump Inlet Strainer.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Replace the Fuel Pump Module.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
5
Turn the ignition off.
Disconnect the fuel pump module harness connector.
Turn the ignition on.
With the DRBIII
t, actuate the ASD Fuel System test.
Using a 12 volt test light connected to ground, probe the (A141) Fuel Pump Relay
Output circuit at the Fuel Pump Module harness connector.
Does the test light illuminate brightly?
All
Yes
→ Go To 6
No
→ Go To 8
Caution: Stop All Actuations.
6
Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Note: Check connectors - It is critical that the connector is free from any
signs of corrosion or deformities - Clean/repair as necessary.
Using a test light connected to battery voltage, probe the (Z1) Fuel Pump ground
circuit at the Fuel Pump Module harness connector.
Does the test light illuminate brightly?
All
Yes
→ Go To 7
No
→ Repair the open/high resistance in the (Z1) fuel pump ground
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
