The starter location on a 1991 Ford Ranger depends slightly on the engine type (2.3L 4-cylinder or 2.9L/3.0L V6) and whether it's a 2WD or 4WD model. However, in general, the starter is located on the
passenger side (right side) of the engine, towards the bottom. You'll likely need to get underneath the truck to access it easily.
To be absolutely certain, you should consult a repair manual specific to your 1991 Ford Ranger's year, engine, and drivetrain. A Haynes or Chilton manual would be helpful for detailed diagrams and instructions.
