Fuel injectors are a common modern car system that supplies fuel to the engine. However, fuel injector issues can prevent a car from starting if the engine light is flashing or illuminated.

Fuel Injector Issues
Fuel injectors are a relatively new technology in cars, with electronic fuel injectors being widely used on European cars starting around 1980. All cars sold in the United States now have fuel injection systems.
The fuel system used in modern cars has changed a lot over the years in trying to keep up with emissions and fuel efficiency laws. Single-point injection was a relatively low-cost way for automakers to reduce exhaust emissions to comply with tightening regulations while providing better "driveability" (easy starting, smooth running, no engine stuttering) than could be obtained with a carburettor.
Fuel and air then mix with each other through either the port or manifold before reaching the combustion chamber. Most cars that are powered by gasoline are injected with fuel indirectly in order to have an appropriate mixture of air and fuel prior to entering the combustion chamber.

Engine Failure
Fuel injectors are a relatively new technology that has been around since the 1950s. Electronic fuel injectors were widely used on European cars starting around 1980. All cars sold in the United States have fuel injection systems.
Fuel injectors are made of various parts, including four injectors. Fuel is delivered to the engine bay via a fuel pump before being injected into the inlet port or manifold. While the fuel is injected, it gets delivered to every cylinder. Fuel and air then mix with each other through either the port or manifold before reaching the combustion chamber. Most cars that are powered by gasoline are injected with fuel indirectly in order to have an appropriate mixture of air and fuel prior to entering the combustion chamber.

Running Out of Gas
Fuel and air then mix with each other through either the port or manifold before reaching the combustion chamber. Most cars that are powered by gasoline are injected with fuel indirectly in order to have an appropriate mixture of air and fuel prior to entering the combustion chamber. Indirect fuel injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or a sophisticated common-rail injection system. The last is the most common system in modern automotive engines.

Dirty Fuel Injector
A fuel injector is a system that delivers fuel to the engine of a car. Fuel injectors have been around since the 1950s, with electronic fuel injectors being widely used on European cars starting around 1980. All cars sold in the United States now have fuel injection systems.
A dirty fuel injector can cause your car to not start because it is supplying too little or too much fuel to the engine. This can be caused by running out of gas, which can also lead to fuel injector issues. If the Check Engine Light comes on, it could mean that the fuel injector is dirty or malfunctioning.

Multi-Port Fuel Injection
The fuel system used in modern cars has changed a lot over the years. The 1990 Subaru Justy was the last car sold in the United States to have a carburetor; the following model year, the Justy had a fuel injector.
In a common-rail system, fuel from the fuel tank is supplied to a common header (called the accumulator), and then sent through tubing to the injectors, which inject it into the combustion chambers.
Fuel injector issues can lead to engine failure that prevents your car from starting. It's also possible that your car won't start because you forgot to put gas in it. Running out of gas can also lead to fuel injector issues. If the engine light on your dashboard is flashing or illuminated it could mean a number of different things that require immediate attention, one of them being a dirty fuel injector.
