Corp. Ref. No.: 606505R
SUBJECT: HOT FUEL STARVATION (VAPOR LOCK)
MODELS AFFECTED: 1986 CENTURYS WITH THE LE2 2.8L V6 ENGINE (VIN CODE X)
With high ambient temperatures, particularly in high altitude areas, some 1986 Centurys equipped with the LE2 2.8L engine may experience a "no restart" or "hard restart" (long crank) condition after being shut off for 10-45 minutes. Other vehicles may start and then immediately stop running. These vehicles may not restart until the engine has cooled down. These conditions may be caused by fuel starvation (vapor lock) and can be repaired by the installation of an engine cooling fan delay relay kit, Part Number 10094719, available from GMSPO. This kit includes an installation instruction sheet.
