I have an 89 honda civic LX. Sometimes it just won't start. It cranks over but will not fire. It does it more in warm weather it seems. I have replaced the main relay, battery and ignition coil, but still have the problem. It has become a problem since I live in san francisco and can't leave it where it is broke down. Any suggestions as to what the problem might be? It is fuel injected as well, and has 148,000 miles.
