Troubleshooting Test Steps
6. Fuel Rail Pressure Relief Valve (PRV)
A. Turn the keyswitch to the OFF position.
B. Disconnect plastic tube assembly (4) from fuel manifold (1). Re-
fer to Disassembly and Assembly, "Fuel Manifold (Rail) - Remove
and Install".
C. Securely seal the end of plastic tube assembly (4).
Note: Plastic tube assembly (4) must be sealed to prevent air in-
gress into the fuel system.
D. Attach a length of hose to fuel manifold (1) and secure with a
clip at position (3).
E. Place the other end of the hose into a container that is suitable
for fuel. Ensure that the hose is secure and will not come out of the
container while the engine is running.
F. Turn the keyswitch to the ON position.
G. If the engine will start, use the electronic service tool to perform
the "High Rail Pressure Test" . This service test will run the engine
with an elevated fuel rail pressure for a limited time. At this pres-
sure, a PRV that is functioning correctly will remain closed. If the
engine will not start, crank the engine for a maximum of 30
seconds.
H. After the engine has stopped, check the container for fuel.
7. High-Pressure Fuel Pump
A. If all previous Test Steps have not identified a fault, and a fuel
rail pressure diagnostic code is still active, replace the high-pres-
sure fuel pump.
Refer to Disassembly and Assembly, "Fuel Injection Pump - Re-
move" and refer to Disassembly and Assembly, "Fuel Injection
Pump - Remove".
B. Run the engine and use the electronic service tool to check for
active diagnostic codes.

Values
Fuel in container Result: Fuel is present in the container.
Install a replacement fuel manifold. Refer to Disassem-
bly and Assembly, "Fuel Manifold (Rail) - Remove and
Install". When the fuel manifold has been replaced, use
the electronic service tool to perform the "Rail Pressure
Valve Learn Reset" .
Result: No fuel is present in the container.
Proceed to Test Step 7.
Result: There are no active diagnostic codes.
Diagnostic codes
Return the engine to service.
Result: A diagnostic code that is not listed in Table 41 is
active.
Troubleshoot the code. Refer to Troubleshooting, "Diag-
nostic Trouble Codes".
Result: One of the diagnostic codes listed in Table 41 is
still active.
Contact the Dealer Solution Network (DSN).

Fuel Level in Tank
If the level in the fuel tank is low, the hot fuel from the
high-pressure fuel system can raise the temperature
in the fuel tank. Replenish the fuel tank at the earliest
opportunity.
Location of the Fuel Tank
Make sure that the fuel tank is not close to a heat
source. If necessary, shield the fuel tank from the
heat source.
