1983 Toyota Cressida ignition is dead but battery is ok?

Answer 1

You need to check:

1. Ignition Coil, Igniter, Distributer, and for faulty Spark plugs .

If you connect a timing light, and check each spark plug wire, you know if your getting spark.

Inspection of Ignition Coil w/Igniter1. Disconnect High Tension Wire2. Measure Coil Resistancea. Disconnect ignition coil connector b. Measure primary coil resistance. Using an ohmmeter, measure the resistance between the positive (+) (brown side) and Negative(-)(blackside) terminals. Primary coil resistance (cold): 0.4-0.5 ohms c. Measure secondary coil resistance. Using an ohmmeter, measure the resistance between the positive (+) terminal (brown side) and the high tension terminal. (the wire to the distributor) Secondary coil resistance (cold): 8.5- 11.5 k ohms3. Connect High Tension WireInspection of igniter1. Turn ignition switch on2. Check Power Source Line Voltagea. Disconnect the brown and yellow wiring connector b. Using a voltmeter, connect the positive (+) probe to the brown connector on the wire harness side and the negative (-) probe to the ground. Voltage: Approx. 12 V3. Check Power Transistor In Ignitera. Connect the brown wiring connector. b. Disconnect the coil cord from the distributor. c. Disconnect the pink and white wiring connector. d. Apply voltage {(2-5 volts the picture uses 2 D sizes batteries, 1.5 volts ea., connected in series} and connect the positive (+) pole of the battery to the pink wire terminal and the negative (-) pole to the body ground. Caution: More than 5 volts would destroy the diodes.e. Check that there is a spark from the coil cord tip, (the wire that goes to the distributor), in about 1 second. If not, replace the igniter. On - Vehcle inspection of Distributor1. Inspect Distributor cap and Rotora. Check for cracks, carbon tracks, burt or corroded terminals. b. Check the distributor center contact for wear. If a problem is foud, replace the component. 2. Check Pickup CoilUsing an ohmmeter, check each resistance of the two pick-up coils. G pickup coil resistance:G (W) - G (Y) slot = 140-180 ohms

Ne pickup coil resistance:Ne (R) - G slot = 140- 180 ohms, does not specify G (Y) or G(W).
