WARNING: When ignition load (spark) testing is required on any
conventional EFI engine (non direct fuel injection), make sure to follow
the safety precautions listed in the Preface Section of this reference
manual. If there are fuel vapors present in the engine, the ignition load
(spark) test could ignite the fuel vapors and cause the engine to
backfire. An engine backfire condition may result in internal engine
damage. Purge fuel vapors from the system if required. Do not remove
flame arrestor if the engine is equipped with one, otherwise a flame
from a engine backfire may ignite fuel vapors and cause a fire or bodily
harm.
