Hi everyone,

I have a 04 Renegade 600 SDI. About 4 weeks ago I purchased a new battery for it. Put battery in and it ran great. Never had any issues with this sled. I drove it down a trail for about 15 minutes. Everything was fine. Yesterday I started it up and idled it for about 10 Minutes...no problems and then moved it to inside a plastic shelter not heated. It got real cold out yesterday.
This morning I started it up, elec. start and wanted to idle it for 5-10 minutes, within 3 or 4 minutes I gave it some gas and it started to backfire and stall. I re-started it up and could not keep it running tried again but idle was real low and not steady. Now it won't run turns over fine, battery is new and keeps turning over but does not fire up. Would anybody be able to give me a suggestion as to what to do.

Thanks everyone,

Paul

are the plugs fouled?

I hope that 10 minute idle was an exaggeration. Shouldn't ever let it idle that long. Yes check your plugs.

Thanks for the reply guys. I did change the plugs with new ones. Yes it was a bit of an exaggeration, but not by much. I really left it run for about 2 minutes, before I started trying to re-start it. It is really cold up here in Haliburton about -18c.....
My son rode it yesterday around our property with no issues. I have also put gas line antifreeze, it prevents gas from moisture. I checked all the relays and fuses...everything seems OK. I even took the 3 relays in there and warmed them up. I checked the battery, which is new anyways. It keeps turning over but does not fire at all. I am lost as to what it could be, it's as though it has no gas, yet there is fuel. I even took an eye dropper and put a little bit of gas in both cylinders, plugs back and tried to fire it up....nothing, how can I check that there is a spark at the tip of the plug. Is it just by pulling spark plug out and leaving rest somewhere and trying to start it??

Thanks very much,

Paul

I had the same thing happen to my 600 sdi, was running great, around the yard a few times pulled it up to the garage and quit just before I backed it into the garage. Cranked it a lot but would not start. Thought maybe compression.

I pulled the plugs, checked compression (130 each side) hooked up the wires and rested on the top of the head, tilted so the bottoms were not touching.

Hit the electric and spark looked very week and not going to the bottom but to the sides. I cleaned the plugs a bit, checked spark again, looked not bad but not bright blue . Then re installed them.

Crank, crank crank still nothing. Thought maybe something else was going.

Did some checks, cleaned plugs again (were wet) thought maybe bad gas. Tried again, nothing.

Pulled plugs, cranked engine to clear any fuel. Put in new plugs and it started right up. But then a large bang when the accumulated fuel in the exhaust lit. Next time I will wait for the gas to evaporate before trying.

I still can’t figure out why cleaning the plugs didn’t work. Maybe there is a special procedure to clean them. I just scrapped the electrode and the contact point.

Good luck with yours.

Thanks very much for your reply....I will try that first thing in the morning. When I did pull the plugs which have about 15-20 runninng time on them, I did find that they were wet with gas. I just wiped them off, they still looked new and put them back. It is too cold up here tonight to try that, but I will let you know if it works.....

Thank you again,

Paul

check your grounds to.i had the ground connection on the battery come loose one time. anytime the skis got air time the sled cut out/bogged until it made contact again. my dad went and rode it, he said it was fine. but the skis never came off the ground when he rode it so the ground never lost connection.

Put a set of br8ecs in it dont let it idel to long the 04 sdi were bad for plug fouling. Just bumb the throttle a little to worm her up just went through the exact same thing. Dosnt matter what u do u cant clean these plugs after they foul. Ive cleaned them cheaked spark looked strong put back in still wouldnt start. Putmy spare ones in fired write up!!

Pull the wires off the plugs and check to see that the terminal inside the wire cap is clean. I took a 3/16' drill, wrapped it in cloth and twisted it around in there to clean out all the carbon build up. I've done that on a couple of other SDIs too while out riding. Helped in my case. You may find the top of the plug all black too, if that's the problem. Good luck.

I had my 03 600ho not start in my garage, had no spark at all. It went to the dealer after playin with it for hours! What it ended up being was the pickup coil. Just a thought hope this helps.

Let us no what it was

[combanx]

Hi everyone,

Well you guys were right, changed out the spark plugs with new ones and away she went. Fired up first shot. I am glad I did not end up bringing to the dealer.
Thank you for all your help.
There is a guy who seems to be having the same problem, think the heading is DON'T KNOW WHAT ELSE TO DO......Hope he has been reading this thread because my spark plugs were brand new. Sled had just run about 15-20 minutes total on them. They fouled and would not allow the motor to fire. Just before it did not start I heard popping too like a muffeled back fire at low RPM...Then I kept trying to start it and eventually it did not fire at all. Why does this happen, are we not suppose to let it idle even for 5 minutes prior to ride?? I could understand if it was warm outside but here today it is about -23c It should never overheat. Anyways Thanks again guys.

Paul
