Condition
A dealer may encounter a customer concern of a hard start or a no start. DTCs P0087, P0088, P0191 or
P128E may also be found.
Normal SI Diagnostics may be inconclusive or lead to Fuel Injection Pump replacement.
Service Procedure
Complete the current SI diagnostics for any symptoms or DTCs found.
If the current SI diagnostic has led to Fuel Injection Pump replacement, Fuel Pressure Regulator 1 must be inspected for debris that can be picked up with a
magnet.
Note: Clean the area around Pressure Regulator 1 before removal. It is possible that road debris could find its way into the regulator port when it is removed. A
small piece of dirt on Pressure Regulator 1 does not qualify for the fuel system repairs recommended in this Bulletin.
1
Remove the Fuel Injection Pump / Pressure Regulator 1 for inspection.
If Pressure Regulator 1 has no debris that can be picked up with a magnet on the screen, continue with Fuel Injection Pump replacement.
2
If there are only a few pieces of debris that can be picked up with a magnet found on Pressure Regulator 1, remove the Fuel Rail Pressure Sensor and/or Fuel
Pressure Regulator 2 (Pressure Relief Valve) for inspection.
3
If additional debris that can NOT be picked up with a magnet (Contamination) is found on the Fuel Pressure Regulator 1, Fuel Rail Pressure Sensor, and/or
Fuel Pressure Regulator 2 (Pressure Relief Valve), refer to PIP5370 and Contaminants-in-Fuel Diagnosis. DO NOT perform the repair listed in this bulletin.
Important: If debris that can be picked up with a magnet as described above is found, complete the repairs listed below:
1.
Replace all of the parts listed in the Parts Information below.
2.
Clean and flush all fuel chassis lines, filter pipes, and other engine mounted fuel system pipes that are not being replaced.
3.
The fuel filter housing must be cleaned with a new fuel filter installed.
4.
The fuel tank and fuel sender must be cleaned and flushed.
Note: The Indirect Fuel Injector (Hydrocarbon Injector) and its fuel lines must be purged of air any time it is removed or replaced. Failure to do so may damage
the injector. Perform the Diesel Particulate Filter (DPF) Regeneration Enable any time the indirect injector or its fuel lines are opened/removed or replaced. This
will force regeneration as soon as conditions allow and will purge any air from the system. Refer to Diesel Particulate Filter (DPF) Regeneration Enable in SI.
TIP:
After repairs, the following may help with fuel system priming:
•
Prime fuel to the fuel filter housing.
•
Relieve air by opening the bleed screw at the filter housing.
4
•
Pump the priming ball again until no more air escapes and close the bleed screw.
•
Prime until the priming ball is hard.
•
There should be at least 10 psi fuel pressure on the fuel system pressure gauge attached to the fuel system service port (schrader valve).
•
Crank the engine for up to 15 seconds.
•
Key off for one minute.
Repeat the above steps until the engine starts. It is normal for the engine to start and then stall when the fuel system loses prime. Repeated priming will alleviate
this concern.
