* 2.3L 4-cylinder: This was a very common and popular engine choice.
* 2.9L V6: A more powerful option than the 4-cylinder.
* 3.0L V6: In some models (especially higher trims or later in the model year), you might find this slightly larger V6.
To know the *specific* engine in a particular 1990 Ford Ranger, you'd need to check the vehicle's identification number (VIN) or the engine bay itself. The engine displacement (e.g., 2.3L, 2.9L) will be clearly visible on the engine block.
