code 12 means thaere is no distributor signal, in other words, it is not running. check the distributor pick up coil. it should ohm out 800-1500 ohms. it was the most common failure. Roy

Thanks roy, but i think code 12 is normal when the engine is not running, isn't it?

yes it is. if it sets with it running, the distributor is failing. Roy
