08 sportsman 800 EFI No start


fishing tech

Recommended Posts

This started lasted Dec with a a longer crank time before it would start. Then it would stumble, hesistate, die. Run good for a while and then repeat. I drain the gas thinking I had water in the fuel, filled with fresh gas. Well yeasturday I drove it around to the back yard to put the plow in the shed. It started hard, struggled to stay running. I got it back to garage and that was it. It will backfire but won't start. I have fuel, haven't checked the psi yet, and seams to have spark. Any common problems with these that I should check? No codes either. It has 354 miles and 84 hour. I use it mostly for ice fishing so it has alot of idle time. Thanks for any help/sugestion you have.

The best part is I bought a 2 year extended warranty and have had it for 2.5 years.arg!

Id pull the Throttle body & clean it with carb cleaner, along with new plugs. Do you have the Polaris service manual? You mentioned a book stating the fuel pressure. I would also check the throttle position sensor & the Tbap sensor. In thier service manual it details how to do it. There is a adapter required to test the TPS, can get thru polaris..I did fine one at kms perfomance for my ranger..never looked at a sportsman with efi..I would imagine its the same setup.

Thanks guys. I am going to replace the champion plugs(not a fan of these) with NGK. and then go from there. The spark seam errattic. So crank sensor gap will be checked and the sensor. Anyone know what the resstance for the sensor should be? I think I measure 573ohms when I checked it.

    • Truly sorry to hear that duffman! I know that feeling.  Keep the good memories  
    • Chamois passed away this weekend a couple days short of her 13th bday. What a great dog to hang out with here at home and on distant adventures. Gonna miss ya big time my little big girl.
    • Sounds pretty sweet, alright. I will check them out, thanks.
    • If you really want to treat your wife (and yourself) with a remote operated trolling motor, the Minn Kota Ulterra is about easy as it gets.  Auto stow and deploy is pretty awesome.  You just have to turn the motor on when you go out and that the last time you have to touch it.   24V 80lb.  60 inch shaft is probably the right length for your boat.  They ain’t cheap - about $3k - but neither one of you would have to leave your seat to use it all day.
    • Wanderer, thanks for your reply. I do intend for it to be 24 volt, with a thrust of 70-80. Spot lock is a must (my wife is looking forward to not being the anchor person any more).  With my old boat we did quite a lot of pulling shad raps and hot n tots, using the trolling motor. Unlikely that we will fish in whitecaps, did plenty of that when I was younger. I also need a wireless remote, not going back to a foot pedal. We do a fair amount of bobber fishing. I don't think I will bother with a depth finder on the trolling motor. I am leaning toward moving my Garmin depth finder from my old boat to the new one, just because I am so used to it and it works well for me. I am 70 years old and kinda set in my ways...
    • Dang, new content and now answers.   First, congrats on the new boat!   My recommendation is to get the most thrust you can in 24V, assuming a boat that size isn’t running 36V.  80 might be tops?  I’m partial to MinnKota.     How do you plan to use the trolling motor is an important question too.     All weather or just nice weather?   Casting a lot or bait dragging?   Bobber or panfish fishing?   Spot lock?  Networked with depth finders?  What brand of depth finders?
    • We have bought a new boat, which we will be picking up this spring. It is an Alumacraft Competitor 165 sport with a 90 horse Yamaha motor. I will be buying and installing a trolling motor,  wondering if I can get some recommendations on what pound thrust I will want for this boat?  Also, I will be selling my old boat, is there a good way to determine the value on an older boat ( mid-80's with a 75 horse 2-stroke  Mariner motor)  I will appreciate any help with these questions.
