Service Information on Fuel Pump Usage

Subject:Service Information on Fuel Pump Usage

Models:All 1993 Saturns



Purpose

Model year 1993 Saturns use two different fuel pumps; a different one for each engine configuration. If the SOHC (LKO) fuel pump is incorrectly installed on a vehicle with a DOHC (LLO) engine, insufficient fuel pressure will be supplied to the engine, resulting fuel pressure will be supplied to the engine, resulting in possible driveability complaints in cold weather. Parts can be visually identified by the label attached to the vent line from the pump.
