OK CONTINUED FROM PAGE FI-11 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) OK ↓ CHECK EFI ELECTRONIC CIRCUIT USING VOLT/OHMMETER NO → 1. Wiring connection 2. Power to ECU (1) Fusible link (2) Fuse (3) No. 1 and No. 2 main relay 3. Air flow meter 4. Water temp. sensor 5. Injection signal circuit (1) Injector wiring (2) Resistor (3) ECU
