10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 - 0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for about three seconds, and check whether spark is generated between the spark plug and the grounded metal
portion.
CAUTION:
• During the operation, alw ays stay 0.5 cm (19.7 in) away
from the spark plug and the igni tion coil. Be careful not to
get an electrical shock wh ile checking, because the elec-
trical discharge voltage becomes 20 kV or more.
• It might cause to damage the igni tion coil if the gap of more than 17 mm (0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the sp ark might be generated even if the coil is mal-
functioning.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace malfunctioning ignition coil with power transistor.
Component Inspection (Condenser-2) INFOID:00000000047803701.
CHECK CONDENSER-2
1. Turn ignition switch OFF.
2. Disconnect condenser-2 harness connector.
3. Check resistance between condenser-2 terminals as per the fol- lowing.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace condenser-2. Spark should be generated. JMBIA0066GB

MALFUNCTION INDICATOR LAMP
MALFUNCTION INDICATOR LAMP
Description INFOID:0000000004780371
The Malfunction Indicator Lamp (MIL) is located on the combination
meter.
The MIL will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
When the engine is started, the MIL should go off. If the MIL remains
on, the on board diagnostic system has detected an engine system
malfunction.
For details, refer to EC-90, " Diagnosis Description " .
Component Function Check INFOID:00000000047803721.
CHECK MIL FUNCTION
1. Turn ignition switch ON.
2. Make sure that MIL lights up.

Checking Fuel Line " .
- Disconnect battery ground cable.
• Always replace O-ring when the fu el gauge retainer is removed.
• Do not kink or twist hose and tube when they are installed.
• Do not tighten hose and clamps excessively to avoid damaging hoses.
• After installation, run engine an d check for fuel leaks at connection.
• Do not attempt to top off the fuel tank afte r the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, r esulting in fuel spray and possibly a fire.
