Why did you defeat the etc switch in the throttle housing? If it's getting spark and fuel,do a compression check along with checking valve clearance. .006 intake and exhaust,compression should range between 55-90 psi on average because of the decompression lever on the cam.A service manual for 5 bucks can show you things to check for.2002 Polaris Sportsman 500 Service Manual PDF Download

Hi again, thank you for answering back, I just purchase a compression tester and I received a result of 80 , and redid it again with the same result. Put plug back in and still the same no luck. We decide to use the pull cord and all we got is a few back fire but we're never able to fire it up, what else you think I should try. Tks

Mine was hard to start it turned out the pulse coil's magnetic face beside the fly wheel was dirty with tiny metal filings stuck to it. I cleaned it up and re gaped it and it's been great since.
Turns out lots off crap works its way down the pull rope hole and into the recoil cover where the pulse coil is located.

Yes like tlc mentioned dirt/trash can cover the face of the pick up coil and also the magnetic strip on the flywheel causing problems also. Before you pull the recoil cover check resistance on the white and white/red wires leading to the cdi module. These are the pick up coil wires. Should show around 97 ohms resistance.If the pick up coil checks out ok,pull the recoil cover and clean these areas,seal the cover,some owners silicone the rope handles to keep water and dirt out. If this doesn't solve the problem,you can check the stator specs from the manual along with other trouble shooting guides it shows.

Once the coil was cleaned it started easily fine both ways.

Hi again, tks for the reply, verified everything you mention everything seems to be good, what I notice I did a ohms reading on my coil for the sparkplug,coil reading was good but from end of sparkplug cap to coil I'm suppose to have 6.4 ohms and I'm reading 11.4 does that mean my plug wire is shot and needs replacing.
