Greetings from the foothills of the Wind River range and a noobie.
I recently acquired a 94 ZR580 EFI from my father-in-law. He has had this issue with it for a few years so he sent it home with me to get a little use out of it. Sled starts great even in very cold temps and runs great too......until you shut it off. Then you have to wait until it cools down (like WAY down) before it will start again. It's the craziest thing and very frustrating as we can't go anywhere with it except around the pasture.
Exactly what happens is this:
- Starts on 1st or second pull every time
- sometimes sits and idles no problems and sometimes need a little throttle feathering to keep it going
- runs GREAT
- You shut it off or let it die after running for awhile
- go to pull start it it and it sputters and tries to start to give you false hope
- you pull and pull and pull until you're worn out and it will not start
- after several hours over night you repeat the above steps starting with firing right up after one or two pulls
I'm thinking some sort of ECM issue? Do these even have ECM's?
I have quite a bit of experience with vehicles both gas and diesel but zero experience with snow mobiles or even 2 cycle stuff. My father-in-law is a sled head and a hill climb pioneer from Logan, UT but is not a mechanic and has had very little time for the last few winters to do anything about it.
Where could I start?
TIA
