My Scooter has Power but it Won't Start

When you buy a scooter and use it for an extended period, one of the common problems that can pop up unexpectedly is an issue with the starter. If you discover that your scooter has battery power, turn on the key and your lights turn on, but can't engage the starter, this could be one of two problems; either the starter itself or your starter switch. Regardless of which one it may be, there is a system we recommend using to trace the problem, and solutions for fixing each one based on your own experience or comfort level.


  1. Try to manually start the scooter: The first thing we recommend is to try and manually start your scooter with the start button on the handlebars. If you turn the key on and engage the button, but nothing happens, the problem is going to be electrical; meaning that it's the starter button, the wires running to the starter relay, the relay itself or the actual starter. If you try to start is manually and the starter engages, but the engine won't fire, then the problem is with the ignition system or fuel system.

  2. Check the Engine Ignition and Fuel System: In most cases, the problem with a scooter not starting but with power is caused by an issue with the engine; either a bad spark plug wire, bad plug or a fuel system problem.
    • Checking the Fuel System: In order to check the fuel system, make sure you inspect the fuel lines running from the fuel tank to the fuel pump and to the actual carburetor / fuel injector. If you notice any leaks, replace the hoses with the new ones. You should also inspect the fuel filter and see if it's clogged up with debris. This is a major reason why engines don't start, especially if you drive your scooter on dirt roads.
    • Checking the Ignition System: The other major reason why an engine won't start is due to the engine not getting the right spark. This is caused by a problem with the spark plug, spark plug wires, or the ignition coil. If you're experienced in these systems, you'll know how to check to see if they are the issue. If not, please don’t' attempt to check electrical components as it could be dangerous and cause injuries. Take your scooter to a certified mechanic to complete this diagnostic check.
  3. Checking the Starter: If the scooter won't engage the starter when you press the button, it's probably due to a bad fuse, or problem with the actual starter motor. In this case, you'll want to inspect the fuses next to the relay or CDI. If the fuses are good, the problem is most likely with the starter and you'll have to order a new one to replace. At this point, contact our sales technicians at Killer Motorsports and order a replacement starter, or contact a local scooter parts supplier or mechanic to see if they can order and replace it for you.

If you've completed the above recommended diagnostic inspections and still are having trouble finding the cause of why your scooter won't start, it is possible that you may have significant engine damage. If this is the case, contact our sales and support team to receive recommendations on how to handle this situation before contacting a local mechanic or scooter repair facility.
