<P> Starting fluid is sprayed into the engine intake near the air filter , or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly . Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one 's arm with pull start engines , especially on rarely used machines . Other uses include cold weather starting , vehicles that run out of fuel and thus require extra time to restore fuel pressure , and sometimes with flooded engines . Mechanics sometimes use it to diagnose starting problems by determining whether the spark and ignition system of the vehicle is functioning ; if the spark is adequate but the fuel delivery system is not , the engine will run until the starting fluid vapors are consumed . It is used more often with carbureted engines than with fuel injection systems . Caution is required when using starting fluid with diesel engines that have preheat systems in the intake or glow - plugs installed , as the starting fluid may pre-ignite , leading to engine damage . </P>
