Service information of ignition system General Some electrical components may be damaged if terminals or connectors are connected or disconnected while the ignition switch is turned to "ON" and current is present. When servicing the ignition system, always follow the steps in the...
Troubleshooting of ignition system Inspect the following before diagnosing the system. Faulty spark plug Loose spark plug cap or spark plug wire connection Water got into the spark plug cap (leaking the ignition coil secondary voltage) If there is no spark at either cylinder,...
Ignition system inspection If no spark jumps at the plug, check all connections for loose or poor contact before measuring each peak voltage. Use the recommended digital multimeter or commercially available digital multimeter with an impedance of 10 MΩ/DCV minimum. The...
Ignition coil primary peak voltage Remove the spark plug cover ( page 3-6 ). Check all system connections before inspection. If the system is disconnected, incorrect peak voltage might be measured. Check cylinder compression and check that the spark plugs are installed correctly in...
Ignition pulse generator peak voltage Check cylinder compression and check that the spark plugs are installed correctly. Remove the seat ( page 2-2 ). Disconnect the ECM 22P gray connector. Connect the peak voltage adapter probes to the connector terminals of the wire harness side....
Ignition coil — removal and installation Front ignition coil Remove the fuel tank ( page 5-50 ). Remove the spark plug caps from the spark plugs ( page 3-6 ). Remove the bolts, ground eyelet and front ignition coil. Disconnect the ignition primary wires from the front ignition coil. Route...
Ignition timing The ignition timing is factory preset and only needs to be checked when an electrical system component is replaced. Warm up the engine to normal operating temperature. Stop the engine. Remove the socket bolts and timing cover. Remove the crankshaft...
