I went out one day and tryed starting it didnt start. Next day tryed again and it didnt start. then a few days later i tryed push starting and it didnt start and then today i put starting fluid threw the throttle body and still didnt start. Then checked to see if it had spark and it did. My father said the engine was trying to start to fast. Does the rx7 86 13b non turbo have a timing belf? where is it at?
and any ideas what it can be or what i can do to fix it? thanks
