CHECK SPARK PLUGS
Max. allowable gap: 1.4 mm (0.055 in.)
Correct insulation resistance:
10 MΩ or more
Precaution: Never attempt to adjust gap
on used platinum tipped spark plug.
— Note —
Check compression pressure if necessary.
(See page EM-6)
NO → 1. Spark plug
2. Compression pressure
Limit: 9.0 kg/cm² (128 psi, 883 kPa)
at 250 rpm
NO → 1. Injector(s) — shorted or leaking
2. Injector wiring(s) between resistor and
ECU shorted
All 3. Cold start injector — leakage
Plugs (See page FI-49)
WET 4. Start injector time switch
(See page FI-71)
