What gas or diesel vehicles have no electronic parts?

It's impossible for a modern gas or diesel vehicle to function without electronic parts. Even the simplest vehicles, like those from the early 20th century, rely on basic electronic components like:

* Ignition system: Spark plugs need an electrical current to fire, which is provided by an ignition coil and distributor (in older vehicles).

* Lighting: Headlights, taillights, and interior lights require electrical power.

* Fuel system: Modern fuel injection systems are completely electronic, even older carbureted engines use electric fuel pumps.

* Sensors: Modern engines use sensors like oxygen sensors, temperature sensors, and mass airflow sensors to monitor and adjust engine performance.

While some older vehicles might have very basic electronic systems, it's impossible to find a modern car or truck without electronic parts. These systems are crucial for performance, safety, and emissions control.

Even the most basic functions rely on electronics:

* Starting the engine requires a starter motor controlled by an ignition switch.

* The fuel gauge and speedometer are electronic displays.

Therefore, it's safe to say that all gas and diesel vehicles today have at least some electronic parts.
