Important: Replacement gaskets, the engine shut-off solenoid and the pump mounted driver are
listed in the Parts Information table of this Special Policy Bulletin.
Replacement procedure differs between the electronic and mechanical pump models.
Important: DO NOT REMOVE THE INJECTION PUMP. PROPER DIAGNOSTICS MUST BE
PERFORMED PRIOR TO ORDERING A REPLACEMENT PUMP. THIS INCLUDES
VERIFICATION OF THE CUSTOMER CONCERN, PERFORMING SERVICE MANUAL
DIAGNOSTICS IN SI, RECORDING THE VALUES, EFI WORKSHEET AND CHECKING FOR
FUEL QUALITY.
Electronic Pump (DS Model) Engine VIN Code F, P, S
If diagnostics indicate that the electronic fuel injection pump cannot be repaired by the dealership,

SERVICE PROCEDURE — INTERNATIONAL COUNTRIES (EXCEPT ISRAEL)
Follow current in-country procedure.
SERVICE PROCEDURE — U.S. AND CANADA ONLY
1. Check the Vehicle Inquiry System (GMVIS) for in-service date and warranty blocks.
2. Prior to removal and request of an injection pump, perform diagnostics based on symptom or
Diagnostic Trouble codes (DTCs). For 1998 or older vehicles, use the 1998 Service
Information. For 1999 and newer vehicles, use the applicable service information for that year.
Always utilize the Diesel EFI Diagnostic Worksheet for all involved model years.
3. Complete the entire Diesel EFI Diagnostic Worksheet by recording the values of the
diagnostics performed. Photocopy the Diesel EFI Diagnostic Worksheet form and attach the
form to the repair order hard copy. When a defective injection pump return is requested, the
repair order and Diagnostic Worksheet must be returned with the defective injection pump.
4. Record the serial number of the removed defective injection pump on the warranty repair
order.
Important: Injection pumps received under this Special Policy have a serial number assigned and
tracked to a specific VIN and TAC case. These numbers are printed on the package label or
packing slip. Parts numbers for Special Policy pumps are also different than injection pumps
purchased from GMSPO. It is imperative that technicians only install Special Policy Injection
pumps on the assigned vehicle (registered TAC case). If a Special Policy pump will not be
installed in the assigned vehicle, call 1-877-446-8227 for disposition of the injection pump.
5. Record the serial number of the new injection pump on the warranty repair order.
6. Hold all defective injection pumps with a copy of the repair order and a copy of the Diagnostic
Worksheet form until the Special Policy warrany claim has been paid. A Corporate Parts
Return Request will be generated. (Refer to Corporate Parts Return SI Bulletin 99-00-89-019B.
All associated failed parts for claims paid under this Special Coverage, including the defective
diesel injection pump, will be returned to the Warranty Parts Center (WPC).
Important: Failure to retain the defective pumps as required above violates the General Motors
Service Policies and Procedures, Article 1.7, with a minimum of $800 (US) debit. Removed

diesel injection pump metal identification tag must remain attached to the
injection pump to avoid a claim debit.
o
All components must remain on the defective diesel injection pump, including: pumpmounted driver, electric fuel shut-off solenoid, stepper motor, etc. in order to avoid a claim
debit.
The servicing dealer is authorized to submit a Special Policy warranty claim for pump
replacement labor time, plus 0.2 hour administration. (See Claim Table ***)
Important: Damage from poor quality or incorrect diesel fuel, or gasoline or water contamination
is not covered under the terms of the 6.5L diesel warranty. For proper diagnostics, refer to SI
Bulletin 99-06-04-047A in order to determine if the vehicle fuel system contains metal
contamination. Be sure to complete the correction for vehicle fuel system metal contamination
before installing the new electronic diesel fuel injection pump.
