92 Honda Accord EX sometimes wont start expecially if its hot outside or you shut it off & try to start it again. Have to wait anywhere from 15 min to 3 hours before it will start again.

It is most certainly the "main relay". It's a small gray (sometimes brown) plastic box tucked up behind the left dash vent. It controls the fuel delivery. It's secured with 10mm on top of your cruise control computer. It would be visible with a flashlight if you lay your head on the floor (with your head almost touching your gas pedal, seriously). Unbolt it, unplug it and then carefully pry of the plastic cover. If you have good eyes or look really CLOSE you'll see the cold solder pin (broken connection). The break will be thinner than a human hair. Heat that pin up with a soldering gun and watch it puddle back into shape to make the connection and you're good for another 100k miles :)

When I turn on my ignition switch if check engine indicator light on i can easily start the engine if there is no light on the check engine it cannot start the engine my remedy is to remove the battery terminal to reset and if the check engine monitor light on i easily start the engine. There is a problem on my computer box?
