Canadian dealerships must follow exchange procedures until August 31, 1998.
Warranty Policy Canada and U.S.
Fuel
Injection pumps are not covered under General Motors and Stanadyne warranty if fuel contamination such as gasoline occurs.
Electronic Injection Pump
Stanadyne will provide a new pump on exchange for vehicles during the first 12 months of ownership of a model year or until December 31, 1998. However, if the pump exceeds 50,000 miles (80,000 km) in the first 12 months, it will be exchanged with a "rebuilt" pump. During the remainder of GM's 5 year/100,000 miles (5/100), Canada S year/ 160,000 km (5/160 km) warranty, the exchange pump will be a same part number "rebuilt" unit.
Mechanical Injection Pump
In the United States, the pump will be repaired (not exchanged) for the entire GM warranty period (5/100). In Canada, (5/160 km) the injection pump is exchanged for "rebuilt" same part number OEM unit. For vehicles outside Stanadyne warranty period (above 50,000 miles or greater than 36 months), Stanadyne will charge the servicing dealer for the exchange pump. If the vehicle is still within the engine warranty, the servicing dealer can submit a warranty claim for reimbursement providing the repair was for warrantable items. A technical assistance case is not required for mechanical injection pumps.
Exchange Procedure
Electronic Injection Pump
The servicing dealer determines if the fuel injection pump requires repair by accurately performing the diagnostic checks on the Diesel EFI Diagnostic Worksheet. If the diagnostic checks lead to the pump, the servicing dealer contacts Technical Assistance for a case number. If Technical Assistance agrees with the diagnosis, a case number is assigned (which the dealer must have to obtain an exchange pump). The servicing dealer must exchange the pump at a participating Stanadyne Service Dealer.
The Stanadyne Service Dealer will require a completed copy of the diagnostic worksheet and a properly completed "GM Request for Warranty" claim form number GSD 475 Chevrolet; and form number TB 421 GMC/Pontiac. The Stanadyne Service Dealer will then exchange the injection pump per the above warranty policies. In the U.S. only the 1998 model year vehicles require a technical assistance case but in Canada, all warranty injection pump repairs require a TAC case regardless of model year.
Mechanical Injection Pump
If diagnoses indicate the fuel injection pump has failed, the servicing dealer will contact a participating Stanadyne Service Dealer and arrange for injection pump repair (U.S.) or exchange (Canada).
The Stanadyne Service Dealer will require a properly completed "GM Request for Warranty" claim form. The Stanadyne Service Dealer will then repair (U.S.) or exchange (Canada) the injection pump per the above warranty policies. Canada dealerships will have to fill out both a GM request for Warranty Repair Claim form and a Diesel EFI Diagnostic Worksheet. In the U.S. a technical assistance case is NOT REQUIRED for any mechanical injection pump regardless of the model year. In Canada, a technical assistance case is required for all in warranty injection pump repair.
Important:
If the defective pump is not returned at the time of exchange, the Stanadyne Service Dealer may invoice the GM dealership up to $900.00 that will be cancelled if the pump is returned to the Stanadyne Service Dealer within 10 days. The servicing dealer is responsible for shipping costs to and from the Stanadyne Service Dealer.
The servicing dealership is authorized to charge for pump R & R, shipping charges and 0.2 hour administration.
