i have a 96 integra and its been starting up fine every day until today
i came home from work and start it and it wont start battery is fine, all i hear is the click from the main relay thats it what to do ?

 

Do you not hear the starter turning over? I might start with that if you don't hear the starter motor doing anything.

 

as stated in HAN.. check your battery terminals.. if they have a bad connection, it could be the problem.. if its clean, try jumping the battery.. if its not turning over at all, bad starter.. tapping it could be a temp. fix, but might as well get a new one..

 

Your battery may run the lights and the radio but it needs tons of power to crank the starter, put a volt meter on it and turn the key, let us know what it shows, 12 volts or drops down to 5 or something. Ignition switches do go bad, is it in park, like mentioned, get it jumped and clean cables and terminals.
