How can you tell if a starting problem is a starter or an ignition switch or a clutch switch in a 94 Honda Accord with manual transmission?

if you turn your key and nothing happens just the dashboard lights come on that would be your clutch start switch. if you hear a grinding sound when trying to start vehicle or a humming sound that would be your starter.if the vehicle cranks fine but for some reason it won't start then you would look at the ignition system(spark plugs,wires,etc) as your first possible cause.
