New battery, oil changed, new fuel filter, new spark plug. When the key is turned, a fast clicking is heard but the engine never tries to turn over or spin. Looking for some help to see what it could be.
I'm no expert but it sounds like a bad connection to me. Make sure your battery terminals are clean by using a wire brush or sand paper on them and also tight. Also, is the battery actually fully charged? New doesn't necessarily mean it's properly charged.
