I have a 86 RX7, its been sitting for about six months, at one of my friends house, he cant get it started, so i gave him 300 dollers for it, it has a new transmission. We cant get it to start, all the spark plugs are firing, the fuel pump works and all, it justa wont turn over. its been sitting the whole time without antifreeze in it. we put some in it, and now when we try to start it it building pressure and blowing the refill cap off, we think the car wont start because of the fuel regulater, we havent tried out that theroy. but maybe someone can help.
