I would check the kill switch or on/off switch as those work by grounding out the ignition system so there is no spark. After that the coil or magneto might be the issue.

Most backfires are caused by improper mixture settings on the carburetor.

If the shocks are worn out, get off the machine and lift up on the back rack. This takes up the slop between the shifter box and the transmission, and usually allows me to shift. I also had an issue with the thin steel plate behind the shifter box. Got a crack in the top , so it was flexing, creating more slop. Welded it shut, good as new.

Hi, Henry, you need to repost your question under the Kawasaki Mule ATV category, not Motorcycles. Thanks, Gregg

Check for water in the fuel. Also check the carburetor bowl for fuel. You can disconnect the fuel line at the valve and run a bit of fuel out, make sure to run in both on and reserve position. The carb has a small fathead screw for a drain. Back it out a few turns to release the content of the bowl. Also check the air filter under the seat. Make sure it’s clean.

Spark plug
Spark Plug lead

in that order, test them all, swap plugs, swap leads, swap coil to find the culprit.

To me it sounds like, possible fuel lines being clogged and maybe need replaced. If you can prime it, and it ??s for 5 to 10 seconds, sounds like its just not getting fuel fast enough or at all through the lines after the initial prime and fire up. Possibly a new fuel pump may be needed. But definitely a fuel system problem. Good luck
