Customer Question

I have a 2002 Polaris 500. After running awhile it starts to cutout, backfire, popping and eventually dies. Won't start again until sits for couple hours. When it does it might run fine for awhile or might repeat same problem right away. Local dealer had it for 6 weeks. Went through carb and air intake. No luck. Finally put a new ecm on saying that was it and sent it home. Still does it.

Hi Doug and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, let's try the basics and determine general area of possible fault. Proposed preliminary tries (if have not been done) when the symptom shows up again:

  • • carefully remove the spark plug;
  • • check the burn color of the ceramic to the tip;
  • • cautiously perform a spark test;
  • • crank and note if fuel enters the combustion chamber.
