Number 10
Date May 1984
SUBJECT: FUEL PUMP MAY FAIL
MODELS AFFECTED: 1984 Skyhawks, Regals, and Rivieras Equipped with 1.8L or 3.8L Turbocharged Engines
General Motors has determined that some 1984 Skyhawks, Regals, and Rivieras equipped with turbo-charged engines were assembled with fuel pumps that may have an early failure of the drive socket. This failure results in insufficient fuel pump pressure to keep the engine running.
