1. Solder small coil connectors
Allow the terminals to cool before covering them
with the connector housings.
Torque the coil mounting screws to 5 N•m
(44 lbf•in).
Install a new locking tie on the rear coil to retain
the wires onto the coil.

SPARK PLUG

Testing for Spark Occurrence
This engine is equipped with two spark plugs that
each receive power from a separate coil. Test
each plug for spark occurrence separately.
WARNING
Never check for ignition spark from an open
coil and/or spark plug as spark may cause po-
tential fuel vapors to ignite.
Use an approved inductive type spark tester to
test each plug for ignition. Follow spark tester
manufacture procedures.
Locate spark plugs on RH side of engine.

pressed, refer to the
If the starter rotates the engine and there is no
spark indicated by the tester, follow the ignition
system troubleshooting sequence as indicated.
If the inductive spark tester indicates ignition to
the spark plug, install a new spark plug.
If a known good spark plug does not solve the
problem, continue testing the other system com-
ponents. The ignition spark may not be correct
due to other system components being out of tol-
erance.
NOTE: Keep in mind that even if there is a spark
during this static test, the voltage requirement to
produce a spark in the combustion chamber is
higher when the engine is running. The ignition
coil may not be functioning properly. Replacing
the applicable ignition coil may be necessary as a
test.
Spark Plug Removal
Disconnect each spark plug cable as required.
