BEFORE YOU START
Always begin with this group to identify a failure in
the engine, fuel or air system. The step-by-step
procedures will provide you with a quick check of the
system. No special tools are required to perform
these checks. If a failure is indicated, you will be
referred to a more detailed check, adjustment, or test.
Always start with the first step and follow the
sequence from left to right. Read each step
completely before performing the check.
This procedure is designed as a quick check of the
system. While performing the check, concentrate only
on the check you are performing and disregard
signals from unrelated components.
