I have a 99 Polaris trailblazer 250 and it has spark, gas,air, and compression, the starter and whole electrical system works too, I'm lost on ideas. Any comments at all would be the best help. Thanks!!!-cam
The throttle switch in the throttle box. If the throttle cable was to break this switch will stop the motor from running. Can be fixed by simply bending the contacts apart (or was it together?). Hope this was helpful!
This seems to be common. Ive got a 2000 with the same issues. Supposedly has a fresh rebuild. Will crank all day. No start on starting fluid. Hook up booster pack and it fires right up and runs. New battery. New plug. New filter. Im leaning toward weak spark. Stator was next on the list. Ill have to check that engine grounding situation
I had one that wouldn't start (all was either replaced or checked out fine.) So, I sprayed some Contact Cleaner inside the cylinder (just a little bit), and bam it cranked right up and was never a problem after that. Don't ask me why. I checked literally that could be checked. And this is what got it going. Believe it or not.
This is a new text My four wheeler is having the same promblem? I got good spark Good compression good fuel but my air box is geting full of oil a mixed gas. I'm mixing 40:1. And it wont start it cranks over brand new battery but won't start even with Any starting fluid or nothing
I have the same problem, I check the spark and it has, I cover the carburetor with my hand and it gets me wet of gas. I already check the compression and it has. It doesn't start with the fluid either. Does anyone knows what's wrong with it?
hey guys im having the EXACT same problem...cannot even get it to start with starting fluid... Ive ordered a new CDI box and coil for it...hopefully it helps...any other suggestions would help...ill let ya know when i get the parts if it helps any...thanks...Nick
Nicholas Barnhill make sure u got spark and if so then check compression I delt with the same problem and first it was the rectifier and then it had spark then I checked compression and for I had 60 pounds so I just rebuilt the top end and runs great same thing with me it would fire on anything lol but it's nice to know now what to check and look for
#1 check fuel #2 check spark #3 check if lower crank is flooded. Remove crank drain screw. Or turn off fuel and stand on tail bar. #4 Check compression #5 Sell on facebook marketplace
so has anyone figured out the problem to this issue im curious mines doing the same thing but i see no on has posted updates on it.... i need help please
I have one with the same issue, good spark, fuel, 115psi compression, stator and coil tested in spec, new cdi, woodruff key is good, won't even fire on starting fluid, go out the next day and it will start and run fine, then won't start again for a month, it makes no sense. I have also unplugged the cdi kill wire to bypass all safety switches and it makes no difference.
@@HorsepowerHouse my trail boss had to get all new crank seals but It kept blowing them put after I put new ones in so I think the crank bering where bad
Hi I just wanted to give my experience with this mine did the same thing for the longest time after a fresh rebuild couldn't figure out for about a year and I'm finally had a bright idea hook a jumper cable to the frame and then the engine and the thing fired right up I was a bad ground from the frame to the engine hope this helps someone
