Can 't get my Apex to fire after storage

[wolfie]

I started my Apex every month or so all spring and summer and it ran fine, but about a month ago, it wouldn't fire. In the spring, I stabilized the gas and parked it last season and that was it for storage prep. It was stored in an unheated, but weathertight shed. Today I tried some starting fluid into the injectors and got it to pop for a couple seconds, but then it would die. Repeated that a half dozen times and the same thing, couldn't keep it running. I dumped some fresh gas in and some Seafoam. I also poured a little down the intakes per their instructions. To add to the aggravation, I think some mice made a home in my exhaust, because plenty of debris is blowing out of the pipes when it runs for a few seconds. I tried the starting fluid procedure another half dozen times, and it was the same thing every time. Fire for a few seconds and die. I wouldnt' think any mice would have anything to do with it not running, and assume I have some intake/fuel issues from storage. Any tips from here?

Couple things, could be the plugs and thats the first place I would start. Second, adding the foam now is too late, you may want to drain the tank then plugs and give it a try. By the way, you should NEVER start the sled unless your going to ride it, and that goes triple for the summer seasonm it does much more harm than good. .

Oh boy, did you say mice. I've heard some tales about them making their way further up than the exhaust.
Your gas is turned on right?

I had mice in my exhaust last year, but the sled started fine. They didn't go any further than the big part of the exhaust. I removed the exhaust and cut it open to get everything out. Then had it welded back. I put steel wool in the end of the exhausts this spring. If you do have to remove it, get new donuts right away.

I thought it might be plugs too, but would they fire at all if the plugs were bad? I have the one size colder plugs in there too fwiw.

If it fires with starting fluid it is getting spark and the plugs are most likely firing just fine. It sounds to me like you are not getting fuel. I would listen for the sound of the fuel pump running inside the tank when the key is turned to the run position. If you do not hear the fuel pump, check the relay. It is located above the left footwell. There are 4 relays located together there and you can switch them around to identify a bad relay. The fuel pump relay is known to fail to close upon cold morning startups. Often simply tapping them will jar it back into operation.

The mention of mice also brings up the possibility that a pesky rodent may have chewed through wiring somewhere on your sled....(Hope not!)...this could make for some headaches getting it back in order.

Hope this helps!

Two places where minnow trap wire mesh comes in handy where the mice like to go, the opening to the exhaust pipes, and the airbox.

Id say yes. I would also recommend highly swapping to the CR10EK"s. Your gonna pull 3-5hp gain just because of the cold plugs. Do a search, lots of info.

Check your airbox and wiring harness,next time you store your sled use a couple small bins filled with kitty litter,it will retain any moisture that is in the shed trailer and it will keep the rodents out!Stay away from the starter fluid it drys the #*$&@ out of the valve guide seals.

CaptianC is right you'll gain with the cr10ek's, just make sure you get the end cap's for them, the cr10ek's don't come with them

I will almost guarentee you just need a set of plugs. They are fouled from starting it and shuting it off all summer. I had the same exact problem this spring with my bike. I would turn over, run for a second, shut off. Then pop and bang and backfire. Threw in a new set of plugs and it fired right up. Good luck

I know that, I ran them all last year. As far as fouled plugs, I don't buy it. I let the motor warm thoroughly, each time and rev out a bit before it got shut off. If its firing with starting fluid, I suspect the plugs are fine and I'm dealing with a fuel issue.

Wolfie,

If I were you, I would eliminate things based on effort, and I think whats the easiest to start with is swapping the plugs first. If you start with fuel, thats a whole diffrent barrel of fish that I wouldnt tackle first. Like I said, I would swap in the CR10eks, worst case they work and you add 3+HP. Good luck.

I am 99.9% certain fresh plugs would fix ya up. Dynotech put those plugs on an Apex & dynoed em & found absolutely zero gains. Maybe his dyno was hooped that day???

I still say plugs, I would bet the bank on it!!!!!! Try a set of plugs, what is it going to hurt?
