GENERAL INFORMATION
1-38
NOTE
A cracked or damaged direct ignition coil or spark plug
cap and cable can cause intermittent problems that are
difficult to diagnose. If the engine occasionally misfires
or cuts out, use a spray bottle to wet the direct ignition
coil or plug cap and plug cable while the engine is
running. Water that enters one of theses areas causes
an arc through the insulating material, causing an
engine misfire.
NOTE
Engine misfire can also be caused by water that enters
through connectors. Check the connectors for loose wire
ends. On waterproof connectors, check for damage
where the wires enter the connector.
6. Perform the Spark Test in this section. If there is a strong spark, perform Step 7. If there is no spark
or if the spark is very weak, refer to Ignition System Testing in Chapter Ten.
7. If the fuel and ignition systems are working correctly, perform a leakdown test (this chapter) and
cylinder compression test. If the leak down test indicates a problem, or the compression under
Engine in this chapter.
Spark Test
Perform a spark test to determine if the ignition system is producing adequate spark. This test
should be performed with a spark tester. A spark tester looks like a spark plug with an adjustable gap
between the center electrode and grounded base. Because the voltage required to jump the spark
tester gap is sufficiently larger than that of a normally gapped spark plug, the test results are more
accurate than with a spark plug. Do not assume that because a spark jumped across a spark plug gap,
the ignition system is working correctly.
Perform this test on the engine when it is both cold and hot, if possible. If the test results are positive
for each test, the ignition system is working correctly.
CAUTION
After removing the direct ignition coil or spark plug cap
and before removing the spark plug in Step 1, clean the
area around the spark plug with compressed air. Dirt
that falls into the cylinder causes rapid engine wear.
1. Disconnect the direct ignition coil or spark plug cap. Check for the presence of water.
2. Visually inspect the spark plug for damage.
3. Connect a spark tester to the direct ignition coil or spark plug cap. Ground the spark tester base (or
spark plug) to a good ground. Position the spark tester or spark plug firing tip away from the open
spark plug hole. Position the spark tester so the electrodes are visible.
