I have a 1988 RX7 convertible with only 11,000 miles on it so it sits alot. We have had problems starting it but now is alright if we start it every day if it sits for longer it does not start. Also when we take it out and make a turn it sometimes just stops running and is hard to restart. We have had it to the Mazda dealer and they can't figure it out any ideas? Also the radio doesn't work. The antenna goes up and you can see the numbers on the digital screen of the station but no sound and it won't take in a CD or Tape any ideas on that? Also the security system and the mirrors are not working now and all these buttons are on a console in between the seats is this a bad fuse?

 

It'd have to be more then one bad fuse, or it could be some animal has crawled into your car and chewed up wires. You need to check fuel, spark plugs, spark plug wires (for the starting problems). Check fuses and wires for the other problems with the radio and other electronics.
