Can you pull start a ATV with a dead battery?

What does it mean when your ATV wont start?
If your engine’s not getting any spark, or getting weak spark, it won’t start at all. The engine will turn over, but will never be able to ignite the fuel and get running.

What happens when you turn off ignition on ATV?
The Ignition key and killswitch are both parts of an electric circuit that, when active, sends an electric signal to the CDI or ECU, telling them to power the coil that then sends a high voltage charge to the spark plug. When you turn off the key or press the kill switch, it is no longer supposed to send a signal to the CDI or ECU.
What happens when the Kill Switch is off on an ATV?
The kill switch is connected in parallel with the wires from the ignition switch. When the kill switch is off, it will send the signal to ground, regardless of the ignition switch position. Focus your troubleshooting on these components, and you have a good chance of finding the cause of your issue.
Why is my fuel pump not working on my ATV?
Troubleshoot a fuel pump that is not working ATVs with traditional carburetors usually have a vacuum-operated fuel pump. They are run by vacuum/pressure pulses created in the crankcase.

If you have a key, the key will need to be in the run position also.
