Ignition Coil

Appearance of Ignition Coil

See the right figure

Fault Description:

If spark plug do not ignite or intermittently ignites,
engine cannot work
If the ignition coil fails and thus the spark plug
does not ignite, the ECU will turn off the injection of
corresponding cylinder, ie, do no inject fuel.
If the high-voltage wire on the ignition coil is
damaged, electrical leakage or poor ignition may be
caused.
Please check: whether the signal grounding from
the ECUJ2-01 pin to ignition coil is conductive, and
whether the connection from the output terminal of
relay to the positive terminal of ignition coil is
conductive.
