Fuel system, gasoline:delivery:fuel pump
Model years: 1998, 1999
Problem: Vehicle description: passenger vehicles. The electrical circuit for the fuel pump is grounded at junction connector g300. If the pin tension is poor, or the bolt securing the connector to the vehicle floor is not tightened sufficiently, a poor connection is made. As the fuel pump operates, the poor connection can create heat which in turn increases resistance. Eventually the fuel pump will not receive enough current to operate.
Risk: This condition could cause the engine to stall, increasing the risk of a crash.
Fix: This corrective action is being performed in conjunction with recall no. 99v317.
Fuel system, gasoline:delivery:fuel pump
Model years: 1998, 1999
Problem: Vehicle description: passenger vehicles. Electrical current to the fuel pump passes through the c304 and c305 connectors. If exposed to moisture, these connectors could corrode. Over time, the fuel pump will not receive enough current to operate.
Risk: This condition could cause the engine to stall, increasing the risk of a crash.
Fix: Dealers will replace the existing connectors and reposition those connectors to an area where the placement is designed to prevent contact with moisture.
