ON-VEHICLE INSPECTION SPARK TEST CHECK THAT SPARK OCCURS (a) Disconnect high-tension cord from the distributor. (b) Hold the end approx. 12.7 mm (0.50 in.) from body of car. (c) See if spark occurs while engine is being cranked. NOTE: To prevent gasoline from being injected from injector during this test, crank the engine for no more than 1-2 seconds at a time. If the spark does not occur, perform the test as follows: SPARK TEST NO CHECK RESISTANCE OF HIGH-TENSION CORDS (See page IG-5) BAD → Replace the cord. OK CHECK POWER SUPPLY TO IGNITION COIL 1. Ignition switch turn to ON. 2. Check that there is battery voltage at ignition coil positive (+) terminal (brown side). BAD → Check wiring between ignition switch to ignition coil. OK CHECK RESISTANCE OF IGNITION COIL Resistance (cold) Primary : 0.4 - 0.5 Ω Secondary: 8.6 - 11.6 kΩ BAD → Replace the ignition coil. OK CHECK RESISTANCE OF DISTRIBUTOR PICK UP COIL Resistance: Approx. 160 Ω BAD → Replace the pick up coil. OK CHECK IGt SIGNAL FROM ECU (See page FI-43) BAD → Check wiring between ECU and distributor, only then try another ECU. OK TRY ANOTHER IGNITER
