If your starter is clicking but not engaging, there are a few things you can try to fix the issue. First, check the battery to make sure it has enough power. If the battery is low, charge it or replace it with a new one. Next, check the connections between the starter and the battery. Make sure they are clean and tight. If they are loose, tighten them. Finally, check the starter itself for damage. If it is damaged, you will need to replace it.
