Stalled Engine - Honda FourTrax Foreman Rubicon TRX500FA5 2019 Owner's Manual

Starting & Stopping the Engine

Stalled Engine

You can restart the engine while the vehicle is stopped by squeezing
the front brake lever and pressing the start/override button.
Do not press the throttle lever while starting in gear. The engine will
not start if the throttle is fully open (because the electronic control
module cuts off the fuel supply).
Once you have started the engine, release the front brake lever, then
apply throttle gradually.
