Fuel temperature sensor voltage/temperature: Normal voltage is 1.58 volts at 35°C (95°F). As the
engine warms up, the voltage should lower (varies with temperature – high temperature equals low
voltage and low temperature equals high voltage). Use a digital multimeter (1994-1996) or a scan tool
(1997-2002) and measure the voltage across the fuel temperature signal (CKT 1578) and the sensor
ground circuit at the sensor harness connector. What is the voltage and temperature?

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 tools, equipment, 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 dealer/retailer for information on

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 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 you. 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.
