Generic Owner Letter
September 2004
Dear General Motors Customer:
As the owner of a 1994–2002 Chevrolet or GMC C/K, G or P model truck, or 1997-1998 B7 school bus, equipped with a 6.5L diesel engine, your satisfaction
with our product is very important to us. Your vehicle was provided with a new vehicle warranty, which covers certain parts of your vehicle for a specified
period. These warranties are of considerable value to you if you should experience problems with your vehicle.
Some owners of 1994–2002 Chevrolet and GMC C/K, G or P model trucks, and 1997-1998 B7 school bus chassis, equipped with a 6.5L diesel engine have
11

experienced a failure of the electronic fuel injection pump. Failure of the pump can cause complaints of poor performance or hard/no start, hesitation, as well as
illumination of the “Service Engine Soon” light.
This is not a recall. Do not take your vehicle to your General Motors dealer as a result of this letter unless you believe that your vehicle has the condition as
described above.

What We Have Done
General Motors is providing owners with additional protection for the electronic diesel injection pump. If a pump failure occurs on your 1994-2002 Chevrolet or
GMC C/K, G or P model truck, or 1997-1998 B7 school bus chassis within eleven (11) years of the date your vehicle was originally placed in service or 120,000
miles (193,000 km), whichever occurs first, the condition will be repaired for you at no charge. Damage from poor quality or incorrect grade diesel fuel, and
gasoline or water contamination is not covered under the terms of the 6.5L diesel warranty or this special policy. This special policy applies ONLY to electronic
diesel fuel injection pump repairs and/or replacement as a result of injection pump failure.

What You Should Do
Repairs and adjustments qualifying under this special coverage must be performed by a GM dealer. You may want to call the service department at the
dealership to find out how long they will need to have your vehicle so that you may schedule the appointment at a time that is convenient for your. This will also
allow your dealer to order parts if they are not already in stock. Keep this letter with your other important glovebox literature for future reference.

Reimbursement
The enclosed form explains what reimbursement is available and how to request reimbursement if you have paid for repairs for the special policy condition.
If the work was done by a Stanadyne dealer or other service establishment, other than a GM dealership, you may not be eligible for reimbursement. Your dealer
will review the case for reimbursement consideration. The amount of reimbursement will generally be limited to the amount that the repair would have cost GM
to have it completed by a GM dealership.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below. The
Customer Assistance Center's hours of operation are from 8:00 AM to 11:00 PM, EST, Monday through Friday.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
