My Unit Won't Start
When you have a situation where your ATV won't start, it's typically due to two reasons; the motor or specifically the starter motor won't engage, or if engaged, the motor won't fire. This means that the culprit is electrical or fuel related. To solve this problem, there are a few steps you should take to troubleshoot and then solve the issue.
- Check the battery If your engine won't crank over, it's most likely an electrical problem. The first thing you should check is the battery and make sure it has a 100% charge. If your battery is fully charged, and your motor wont crank over, make sure to verify that the kill switch is pulled out. If this is not the problem, it's most likely a damaged starter motor and should be examined or replaced by a professional mechanic.
- Check the fuel system If the engine on your ATV will crank over, but won't fire, it's going to be either a fuel or electrical related issue. To determine if it's a fuel problem, you should inspect the fuel line that runs from the gas tank to the fuel pump. You'll want to make sure that there is nothing in the fuel line or that there are no pinches in the line that might cause fuel flow restriction. If you notice any obstructions, or objects in the fuel line, remove the fuel line and clean. Reattach the fuel line and test the solution.
- Check the ignition system Remove your spark plug and put the plug back into the ignition coil, hold the coil with your handle and put the plug onto a ground or the engine, then have someone try to start it; see if the spark plug starts. If the plug does not spark, change your plug with a new spark plug and retest. If it still doesn't spark, then you most likely have a faulty ignition coil.
These three issues are the most common problems that are found with an ATV that won't start. If you've tried all three of these areas, or simply don't feel comfortable with this type of maintenance, contact a local ATV mechanic or call our service department at Killer Motorsports for recommendations.
