To troubleshoot the ignition system of a 1998 GMC Jimmy, first check the battery to ensure it has a full charge and clean connections. Next, inspect the ignition coil and spark plugs for wear or damage, replacing them if necessary. Use a multimeter to test the ignition switch and wiring for any faults. Finally, check for any trouble codes using an OBD-II scanner to identify specific issues within the ignition system.
