turn key nothing
Asked by Bellada Mar 19, 2015 at 06:08 AM about the 1993 Mazda MX-5 Miata
Question type: Maintenance & Repair
Battery is good. Headlights come on everything else is dead ? I figure it may be some fuse? I store the car every winter and this is a first. Owners manual does not really show an ignition fuse per say. Any ideas?

I would check the fusable link as shown in the pic below, there two bolts that hold it in place and the battery should be disconneted before removing. and it could be a bad or dirty contact in the ignition switch. There are good write ups on both of these issues on miata.net.
Also double check the battery and connections as these can be a weak point on these cars.
More than likely it's the ignition contacts. I recently started having issues with car not starting, turn key and nothing, later it would start without hesitation. Also the buzzer comes on when key is not in ignition, it's sparatic. Lights come on, radio, it's crazy. Like the power window contacts, in time ignition contacts build up garbage on them and start screwing with everything.
Mine had the exact same problem on my NC; Turn key, nothing. IT was the 20 amp fuse labeled 'ST'. I don't know what made it blow but replaced it and it started. It is in the engine bay fuse box.
Just like what Perry said, my 2007 Miata NC frequently blows the 20 amp ST (starter) fuse and even though everything electric on the car works, it won't start until I replaced the fuse. I still don't know what is blowing the fuse.
