the relay will make a clicking noise. you would be better checking it with a test lamp or volt meter and check that you are getting power at the starter. there will be a constant feed at the starter and once you turn the ignition on to the start you will get another feed going to the starter on a smaller wire than the main feed. hope this helps. also might try giving it a boost of the battery as if its sat for any length of time it will have drained it
