Troubleshooting Tips When Your ATV Won’t Start With the Switch, But Pull Starts

The ATV will only start with a pull start, not when using the switch.

Atv Will Pull Start But Wont Start With Switch

When it comes to starting an ATV, there are generally two methods involved: pull-starting and switch-starting. When an ATV won’t start with a switch, but will still pull start, the likely cause could be a number of issues such as: a problem with the ignition switch, a faulty starter relay or solenoid, insufficient charge or voltage in the battery, or an issue with the starter itself. In any case, it is always recommended to bring your ATV to a certified technician for assessment. Depending on the issue, they may be able to diagnose and repair your ATV in order to get it started again.

Troubleshooting Pull Start Issues

The first step to troubleshooting an ATV that pull starts, but won’t start using the switch, is to check the spark plug. A dirty or worn spark plug can prevent the engine from firing up. If the spark plug is dirty, clean it with a wire brush and inspect it for signs of wear or damage. If it has been damaged, replace it with a new one.

The next step is to reattach the pull start cord. It’s possible that the cord has become detached from its housing and needs to be reattached before it will work properly. Make sure all connections are secure and there are no visible signs of damage before attempting to start the engine again.

Testing The Ignition System

In order to determine if the ignition system is working properly, you’ll need to check all wiring connections for any signs of corrosion or loose connections. Once this has been done, you can then test the ignition switch by turning it on and off several times while listening for any clicking noises coming from the switch itself. If you don’t hear any clicking noises, then you may need to replace the switch with a new one.

Troubleshooting The Safety Switches

Safety switches are an important part of any ATV’s ignition system and these should be checked if your ATV won’t start using its switch. Check that the kill switch is in its proper position and that it’s functioning correctly by trying to turn on the engine while holding down this switch. Additionally, verify that the throttle lever is in its off position as this can also cause problems with starting an ATV.

Checking Fuel System Components

The fuel system components should also be inspected when troubleshooting an ATV that won’t start using its switch. Make sure all zip ties and boot clamps are secure and in good condition as these parts help keep fuel lines in place so they don’t become loose or disconnected from their respective ports. Additionally, analyze your fuel filter and carburetor hoses for any signs of blockage or damage that could prevent fuel from reaching your engine’s combustion chamber properly.

Possible Electrical Component Malfunction

In some cases, an electrical component such as your voltage regulator may be malfunctioning which could prevent your ATV from starting when using its switch. Inspect your voltage regulator for any signs of faults such as burnt out circuits or loose wires before attempting to start your ATV again using its switch. Additionally, testing your ignition coil resistance can help determine if there are any issues with this component as well and help pinpoint where a problem may exist in order to resolve it quickly and easily without having to purchase expensive replacement parts unnecessarily.

Faulty Choke Setting or Choke Plate Malfunction

One of the most common reasons why an ATV won’t start with the switch but will pull start is a fault in the choke setting or a malfunctioning choke plate. To check for this, you need to first check the float bowl content level and then replace or clean out the carburetor jet. If this does not fix the issue, then you need to move onto other possible causes.

Analyzing Faulty CDI Unit Components

The next step is to analyze faulty CDI unit components. This includes testing the CDI gas discharge capacitor and conducting an oscilloscope CDI unit analysis. If any of these tests are not successful, then it’s likely that the CDI unit itself needs to be replaced.

Alternately Reseting Vehicle ECU

In some cases, resetting the vehicle ECU can help resolve issues with an ATV not starting with a switch but will pull start. To reset your vehicle ECU, start by checking for any ECU fuse block damage and then verifying ECU relay status. If all is well, you can proceed to resetting your vehicle’s ECU by following manufacturer instructions or consulting a professional mechanic.

Based on the given information, it appears that the ATV is having trouble starting with the switch. It is likely that the switch or its wiring is malfunctioning and needs to be replaced. If the switch is functioning correctly, then there might be another underlying issue such as dirty spark plugs or a faulty spark plug wire. It is important to troubleshoot and diagnose the ATV in order to determine and fix the underlying problem.
