To troubleshoot the engine light issue in a 1997 Ford Ranger, first check the fuse diagram located in the owner's manual or on the fuse box cover. Look for the fuse related to the Engine Control Module (ECM) or Check Engine light, often labeled as "ECM," "IGN," or "CHECK ENGINE." If the fuse is blown, replace it and see if the engine light activates. If the fuse is intact and the light remains off, further diagnostics may be needed to identify any underlying issues with the vehicle's systems.
