My wife's '90 Accord LX has a problem starting sometimes. It seems to happen during the summer / warmer weather. When you turn the key you hear all the right sounds but the engine just won't fire up. The battery is good. The wires & plugs are also good. My wife says that if she gives it five minutes or so after it doesn't start then it will fire right up. My buddy's '90 Legend has the same problem. I did a search & nothing really seemd to fit my situation. Ideas?
