Guys,

I have been having starting problems with a 2007 EFI Sportman 500 since the late winter. It has 131 miles on it ... so is not old. Was outside more than it should have been. (Battery has been replaced and is on a battery tender.)

I have disconnected each of the connectors I can reach, cleaned them, and replaced the dielectric grease.

Symptoms:

1) Sounds different when the key is turned in 4WD and 2WD. In 4WD it makes a low hum (I think that is the fuel pump). In 2WD it makes that hum for some seconds and then the injectors click and it goes back to the low hum.

2) Console does not light (show any numbers) while this is going on.

3) If I run 5 to 10 second bursts of the key on with the switch in 4WD maybe five times, then switch to 2WD ... the console will sometimes light and act normally. If that happens, the bike starts immediately and runs fine!

4) If it has started, it will restart relatively easily for a while. The longer it goes, the less likely it is to start.

Guys ... I REALLY need some help here. I can't afford to take this thing to the dealer and get hit with a $1,000 bill to fix it!!!

Would sure appreciate your thoughts!

Is your ATV on the electronic control modules (ECM) recall list,That brain box controlls more things then it should.

 

how do you find out if your machine is on the list?

 

Just google " Polaris ATV Recalls" and look around.

 

My 2007 EFI Sportman 500 is not on the recall list.

I did a lot of searching. I did not find any recalls on the 2007 500 ho x2. I read many complaints about the Polaris's realiablity issues and problems. I bought used with only 30 miles. I put another 50 the first weekend with no issues. Wife will kill me if I have to put a ton of money into maintenance. I ride DS on a honda xr650l. I am spoiled with low maintenace and bulletproof.

 

I have a '04 polaris sportsman 500 HO and i know that if my speedo is not plugged in the whole way it should be, the machine will die right after you start it and it will not run right at all.....also, the 4 wd will not work.....Hoipe this helps......
