SERVICE INFORMATION
Analysis of returned parts has determined that any residual damage to the connector may result in a voltage drop across the module and can lead to repeat failures. Therefore, GM Engineering is advising technicians to replace the connector anytime the Fuel Tank Module/Fuel Pump Module is replaced.
IMPORTANT:
Not all vehicles were built with the Metri-Pack 150 Connector. Refer to the diagrams for identification of the connectors. This bulletin ONLY applies to vehicles equipped with the Metri-Pack 150 Connector. If the vehicle is equipped with the GT 280 Connector, disregard this bulletin.
NOTE:
Do not insert test equipment probes into the connector. The diameter of the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will result in a system failure. To check the integrity of the new splice, the appropriate test probe for this terminal is a Gray J 35616-2A. Do not use paper clips or other substitutes to probe terminals. Using a larger terminal test adapter will damage the terminal.
IMPORTANT:
It is important to use the splice sleeves provided with the connector due to the exposure to moisture. Refer to Splicing Copper Wire Using Splice Sleeves in SI for proper splicing procedures.
