• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

So I was having issues in the past with a fault code and was not able to get it to a shop for repairs as I had only this to commute with (truck broke down). So as I was sitting in traffic it started to run rough at lower rpm's (10-15 mph) I limp the bike home and after a day sitting in my garage I decide to start it and investigate it. It turns over but doesn't start. I'm assuming it's a fuel issue but because I'm not a mechanic, much less a motorcycle mechanic but don't know where to start. Any help would be greatly appreciated.

Easy first check is water temp sensor. Does the fan come on when you turn ignition on? If so sensor has failed. You can try pulling the lead off the sensor and trying to start bike but this will result in fault code being stored in ECU.

Fan does not come on when you turn ignition on Dave. Should I still pull the lead sensor off? I'm pulling plastics and seat off to get a better look at things. I may end up taking it to this European cycle shop close to my house to have them diagnose then determine whether it's a fix I can tackle myself or if I need to hire the work out to them.However if there are things I can check prior to taking it to them then I will.
 
Thought about also draining the fuel and pulling the tank off to see if I can find the fuel filter and maybe change that out too....?
 
Ive had bad water temp sensors that didnt kick the fan on prematurely like most. Ran or barely ran like crap though.. tps once went wacked out of adjustment too and ran just as crappy until reset by dealer.. fouled plug from the previous as well.. also sometimes a battery can have enough left to turn it over but not fire it if its on its way out.
 
Battery is on the tender charging so I'm thinking it's good but like you say if it's on it's way out there's one more thing to look into.
 
They don't always put the fan on - try pulling the lead off the sensor, see if it makes any difference.

I took the tank off to get the spark plug out and see if I had a fouled plug and maybe replace it. Plug looks good but I think I'll change it while it's out. While the tank is off I went ahead and took the fuel in and out module out and found the fuel filter. When I got the filter off I noticed that the fuel in the filter was black. Almost as if it was mixed fuel. After I change the filter I'm going to put the tank back on and see if this could have been the cause. Is there anything else I can do to it while I have the tank off?
 
Where exactly is the water temp sensor? Maybe I can pull the lead off while the tank is off. Is this going to be a plug that goes into the radiator? Sorry I have no idea. Just guessing based on a logistical standpoint. Or is it the group of wires coming off the fan?
 
Right side of bike.. next to spark plug I believe.. may or may not have to remove tank to pull it. Loks like typical water temp sensor.. brass colored, black connector, 2 or 3 wires if IIRC.
 
I took the water temp sensor off and the fan kicked on. Bike still wont start. I sprayed a little starting fluid into it and it will start but wont continue running. My thoughts are that since there's spark it's a fuel issue. Maybe fuel pump? I took it to a place that services European cycle and to my surprise he wasn't open during the hours stated on the phone message. The other dealer I was referred to that does service Husqvarna is in Everett Wa. which is just over an hours drive away. As my luck would have it, he isn't open today. Thinking I may go back back to a Japanese bike once this one is fixed. Seems like a lot of hassle to get it into a place that services these bikes.

Sounds fuel related. Can you hear the pump run when you turn on the key? Fuel pump fuse? May want to get an inexpensive Harbor Freight fuel press test kit and check it if you feel comfortable getting in that far. Or just order a fuel pump and replace it. Your symptoms sure sound like a fuel pump that took a hike.

I can hear the pump kick on when I turn the ignition on. I know at least the initial pressurization is there but the pressure needed to keep it going? Thats a whole different animal right? This was the case with my boat. Initial pressure was there to start the boat but the constant pressure to keep it running wasn't. So I had the tank off of it and when I changed the fuel filter I'm assuming the pump was what was right next to the filter. Maybe?
 
The 630 pump in in the tank, I assume it's the same on the FI 610s. If it is building pressure when you turn on the key it should start for a while at least. If the bike starts on starter fluid then your problem is either no fuel pressure or the ecu is not firing the injector for some reason. I would "T" a pressure gauge into the fuel line and see what is going on.

What did you mean when you said you had fault codes in the past?


.
 
A temp sensor being like 20$ you really should try a new one before you stress yourself. Half the time just pullin it off doesnt tell you jack..
 
DynoBob-The fault code I mentioned in the past is where the nuetral light will come on solid for a second then blink three times and then go solid. It would do that while the bike was running. I was told to put the bike one the "I-beat" software to determine what that code meant.

LRPct-As far as the temp sensor goes, I've decided to wait till tuesday and bring it to the Husky dealer. I was just stressin because I live in Washington state and it rains 9 months a year here and we've been having nice ride weather and my bike is down. The Husky dealers here are an hour away : ( I'll let them diagnose then decide if it's a fix I will take on myself or let them do.

BTW I do appreciate everyone's responses. I'm not a bike mechanic but I do wrench on my own toys to save money. Seems like between youtube and forums like this, you can damn near eliminate the need for hiring a mechanic (with a lot of things. not all)

If the tempsensor goes off, like it did on mine, the bike will run - but be a pain to start from cold. If you have spark and air, it could be petrol thats the problem. Remove the petrol flter and try without it, ore buy a new one from a car parts store ( like a paper inline disposable one )
Also check all - and I mean all - electrical connectors on the bike, if you have injection, check the connection on the throtle body, the injector, etc..... should be clean with no green stuff ( corrosion ) etc inside..
 
I've checked all the plug connections and they all appear to be in good condition. Bought a new filter from an auto parts store and installed it. No go. I have not put a "T" on the fuel line to check for pressure yet. What should the psi reading be at? My neighbor is by no means a bike mechanic but is a wealth of knowledge in the automotive field. He seems to think it's the TPS. I don't remember what the explanation was that he gave me but at the time it made sense. The bike will fire will a small shot of starting fluid but as soon as that's gone ( 1 second ) it dies. Turn it over again without the ether and nothing.
 
I see no spec in the TE service manual for fuel pressure. I'd expect it to be 30-40 psi.

If you probe the wires going to the TPS one of them should vary roughly between 0-5 volts as you twist the throttle.

Did you put fresh gas in after you drained the tank?


.
 
My 630 injector requires 3 bar which is 43 psi, my fuel pressure is 45 psi.

If it fires with ether you have a fuel problem, low fuel psi, clogged injector, broken wire or bad ECM. If all mechanical is OK, good compression and valves adjusted, intake boot not cracked etc....

Check fuel psi at least 45psi, then make sure injector is getting signal from ECM, fix wiring or replace ECM if no signal, then clean or replace injector.
