In this section, we'll cover diagnostic equipment usage. As an
automotive activity, diagnosing modern vehicles has become
extremely high-tech oriented and difficult. Few professions involve
so much from their practitioner. A modern technician has to master
a multitude of disciplines, including electronics, optics,
mechanics, programming, computer science and many others. Such
highly technological activities require a keen analytical mind. But
as in any human endeavors, proficiency comes with practice and
patience. The techniques presented in this section combined with
the necessary hands on practice are designed to sharpen the
technician's abilities to perform profitable and fast diagnostics.
With patience and practice, any vehicle can be repaired. Enjoy

EFI operation, non-sequential and sequential injection, Direct
injection, fuel pulse testing, noid light, injector voltage supply,
scanner, the switched side, engine speed signal, injector current)
* NO START/NO SPARK REPAIR PROCEDURE - (Visuals, secondary,
ignition grounds, ignition power, primary side, ignition neon noid)
* NO START GENERAL REPAIR PROCEDURE - (procedures that should be
used to diagnose a no start, cranks ok condition, spark, pressure,
fuel) * NOTES
