Initial Inspection and Diagnostic Overview

NOTE: Before beginning any troubleshooting of ignition system, verify that all fuses, fuse links and battery connections are in good order.

1. While cranking engine, hold coil wire 1/4 inch from good ground. If coil wire sparks to ground, proceed to step 2. If coil wire does not spark to ground, proceed to step 5.
2. Connect coil wire, then disconnect spark plug cable from spark plug. Crank engine while checking spark to ground. If spark occurs, problem is not in ignition system. If spark does not occur, proceed to step 3.
3. Check condition of spark plug wires, distributor cap and rotor. Repair or replace as necessary.
4. On all models, check voltage between coil primary winding positive terminal and good ground with ignition switch in ON position. Battery voltage should be present.
5. If voltage is not present, check wiring from coil primary winding negative terminal to igniter. Also, check ignition coil resistance.
6. If battery voltage is present in step 5, check voltage between coil primary winding positive and negative terminal with engine cranking. Voltage should be 1-3 volts.
8. If voltage is present, check ignition coil primary and secondary winding resistance. Also, check spark plug wire resistance.
9. If battery voltage is not present, check wiring from ignition coil to igniter. If battery voltage is present, see COMPONENT TESTING.
