How do you use starter fluid for fuel injection?

You do not use starter fluid for a fuel injection system. Starter fluid is a flammable liquid that is used to help start engines that are not getting enough fuel. It is sprayed into the engine's intake manifold, where it vaporises and mixes with the air. This mixture is then ignited by the spark plug, which causes the engine to start.

Fuel injection systems do not use starter fluid because they already have a way to get fuel into the engine. The fuel injector sprays fuel directly into the cylinder, where it is mixed with the air and ignited by the spark plug. This process is much more efficient than using starter fluid, and it does not require any special tools or skills.
