HESITATION, SAG, LOSS OF POWER ENGINE WILL NOT RUN. Oldsmobile Cutlass Ciera 1993

DCS MESSAGE TO ALL OLDSMOBILE DEALERS

CONDITION: SOME 1993 CUTLASS CIERAS WITH 3300 ENGINES MAY EXPERIENCE HESITATION, SAG, LOSS OF POWER, OR ENGINE WILL NOT RUN.

CAUSE: LOSS OF FUEL PRESSURE CAUSED BY SOME CONTAMINANTS IN THE FUEL TANK RESTRICTING THE FUEL PUMP STRAINER. THIS MAY BE CAUSED BY THE DIE LUBRICANT NOT BEING COMPLETELY RINSED OUT IN THE MANUFACTURE OF THE FUEL TANKS. THIS WILL APPEAR AS A GEL OR SOAP OR SLIMY FEEL OF THE FUEL PUMP STRAINER.

CORRECTION: FOLLOW THE SERVICE MANUAL PROCEDURES WHEN DIAGNOSING FUEL RELATED PROBLEMS. THE VEHICLE MAY NEED TO BE OPERATED UNDER A LOAD TO DETECT THE PROBLEM. MAKE CERTAIN THE FUEL SYSTEM IS PERFORMING TO SPECIFICATIONS BEFORE OTHER ENGINE CONTROL SYSTEM COMPONENTS ARE SERVICED.

IF THE FUEL HAS A CLOUDY APPEARANCE OR THE STRAINER IS RESTRICTED, DRAIN OUT ALL FUEL IN TANK FOLLOWING APPROVED REMOVAL PROCEDURES. FLUSH THE TANK WITH WARM WATER FOR 5 MINUTES, (DIE LUBRICANT IS ONLY WATER SOLUBLE AND IS BIO-DEGRADABLE). REMOVE ALL WATER, THIS IS EXTREMELY IMPORTANT BECAUSE THE BAFFLES IN THE TANK MAY BLOCK THE DRAINING PROCESS. ADD A CAN OF "FUEL ADDITIVE" P/N 1051516 TO AID IN COMPLETE REMOVAL OF ALL WATER. REPLACE FUEL PUMP STRAINER WITH P/N 25121754. DO NOT REPLACE THE FUEL PUMP.

PARTS ARE CURRENTLY AVAILABLE THROUGH GMSPO.
