Bought a 2010 wide track 600 ace last spring, he said he only used it once or twice a season which is why it had low hours. Siphoned all the gas out and put fresh in last spring. Put some heat in it before I started running it this winter. Ran great then last time I used it it was idling a little rough but otherwise ran fine. Tried to start it today but wouldn't fire up, put a space heater under it for over an hour but it still won't fire. I'm fairly new to these machines so not sure what the issue might be, anyone have any ideas or similar issues?

The only time I’ve had trouble starting mine is when I’ve had water in the fuel line somewhere. It would start in the garage fine but not outside below 10 degrees. It took 2 jugs of iso heet to cure the problem.

I pulled the run relay and brought it in for the night, will try again in the morning.

Does it turn over and just not start? I have same thing but a 2017. I do a lot of start and stopping and have gone through two starters. Also the batteries sometimes have a bad connection on the ground. I put star washers on my negative and made a double ground.

Yes turns over just wont fire up. Checked the battery and ground. The relay is a shot in the dark but a buddy of mine said it's happed to him a few times. It ran great till it dropped sub zero so i'm thinking maybe water in fuel.

Might need another shot of heat. I use it weekly, especially the morning after a long hot powder burning run. That stuff only last a few minutes before its burned through. I am no expert on the newfangle machines though.

Tarnish Sediment( not used much) has been loosened up and could be blocking the fuel lines...any in-fine filters ?

I believe you're supposed to use the yellow bottle of heet in 4 stroke engines.

I've had the in tank fuel filters clog up and cause that.

Put the relay back and tried it a few times, now the engine light comes on with 4 short beeps- engine fault see dealer.

Disconnect the battery and let it sit for an hour. Reconnect and try.

Check your battery voltage, they dont like to start or stay running if its below 12 volts. Also I would disconnect the fuel line and see if it is pumping fuel and what the fuel looks like. Contaminated fuel or clogged fuel filters are a common issue with them. There are some good writeups on dootalk about how to get to the in tank fuel filter and the screen behind the fuel pressure regulator that also gets clogged.

Usually when its a relay issue they dont turn over or they will sometimes and not other times. Check the connections for the relay its a common source of corrosion. Same with the ground cable connection on the chassis.

The ACE engines are amazing but they do suffer from fuel and electrical issues at times.

Do you have spark? I also seen the line in the tank rotted.

Had similar. Get booster cables and ground from the negative post to the running board. Positive cable not need to be connected. If starts then ground your problem.

I know you said you checked the ground but just in case try above unless you already checked that way.

This is why I don't buy computer controlled crap if there are any other options.

Sounds like you need to change the filter sock in the tank or the pump itself the filter sock is the most common problem with them when it comes to fuel issues especially if you are using heet there kinda a PIA to change out but can be done there is an inline filter that you will see when changing the sock make sure and change it at the same time at least on the newer models

friend had the same problem and as the second tank of gas went through with a little sputtering.....been running smooth since then
one of the good optiums of raising off the floor when in storage so any lightning strikes near-by dont fry the puters...it does not take much

At this point have you been able to get the engine started or just the lights and beeps you describe?
As mentioned is the battery fully charged and is the starter turning the engine over strongly?

Tried disconnecting the battery and waiting for an hour and also tried the jumpercable to the running board but no go. I don't think it's the filters or fuel pump because when I ran it two days before I have plenty of power and there was no bogging down or sputtering. Battery is good and the starter cranks just fine it just doesn't fire. After trying to start a couple times the engine light comes on with 4 short beats. Don't have time to mess with it anymore right now.
