What year did GM go to fuel injection?
General Motors (GM) began transitioning its vehicle lineup to fuel injection in the late 1970s and early 1980s, marking a significant shift away from traditional carburetors. This change was driven by the need to improve fuel efficiency and meet stricter emissions regulations.
The Transition to Fuel Injection
Prior to the 1970s, most GM vehicles were equipped with carburetors, which used a mechanical system to mix air and fuel for the engine. However, as environmental concerns and fuel economy became more pressing, GM recognized the need to adopt more advanced fuel delivery technologies.
The first GM vehicle to feature fuel injection was the 1980 Cadillac Seville. This luxury sedan was equipped with a Bosch-designed electronic fuel injection system, which provided improved fuel efficiency and reduced emissions compared to the carburetor-equipped models.
Following the success of the Seville, GM began rolling out fuel injection across its other vehicle lines in the early 1980s. By the mid-1980s, fuel injection had become the standard for most GM models, with carburetors being phased out entirely.
The Benefits of Fuel Injection
- Improved fuel efficiency: Fuel injection systems are more precise in delivering the optimal air-fuel mixture, leading to better fuel economy.
- Reduced emissions: Fuel injection technology helps engines burn fuel more cleanly, reducing the release of harmful pollutants into the environment.
- Enhanced performance: Fuel injection systems can provide more responsive acceleration and better overall engine performance compared to carburetors.
The transition to fuel injection was a significant milestone in GM's history, as the company sought to adapt to changing market demands and environmental regulations. This shift helped GM maintain its position as a leading automaker and paved the way for further advancements in engine technology.
What year did Chevrolet have fuel injection?
1957
1957 WAS THE FIRST YEAR CHEVROLET USED A FUEL INJECTION SYSTEM ON THEIR CARS. IT WAS INSTALLED ON A 265 CI V8.
When did Corvettes stop using carburetors?
In 1981, Chevy produced its last carbureted engine for the Corvette. In 1982, the Corvette introduced a new generation of fuel injection with the 190 horsepower Crossfire 5.7L engine.
When did GM stop using carburetors?
GM stopped using carburetors in the early 1990s, with the last vehicles featuring them being certain full-size station wagons in 1990. This shift was driven by the need to meet stricter emissions standards and the superior efficiency and performance of electronic fuel injection (EFI) systems.
- The last GM carbureted models: The final new passenger cars with carburetors from GM were the 1990 model year, which included Oldsmobile and Buick station wagons with the Oldsmobile 307 cubic-inch V8 engine.
- The transition to EFI: The move to fuel injection was a gradual process for all automakers, starting in the 1950s for some high-performance models and accelerating rapidly in the 1980s due to increasing fuel economy and emissions regulations.
- Advantages of fuel injection: EFI systems proved to be more precise at metering fuel, which is essential for modern catalytic converters to work effectively and meet emissions targets. They also offered better performance, fuel economy, and cold-start drivability compared to carburetors.
Is a 1993 Chevy Silverado fuel injected?
Yes, a 1993 Chevy Silverado is fuel-injected. By this time, fuel injection, often in the form of throttle body injection (TBI), had largely replaced carburetors in gasoline engines due to the need for more precise fuel/air mixture control for emissions regulations and catalytic converters.

- Technology: The 1993 Silverado used a computer-controlled fuel injection system, specifically a throttle body injection (TBI) system for most models.
- Engine options: Both the available engines (like the 4.3L V6 and 5.7L V8) were equipped with fuel injection.
- Historical context: Fuel injection was becoming standard by the late 1980s and early 1990s, primarily because it allowed for the precise control of the air-fuel ratio needed for catalytic converters to function efficiently.
