grizzly yamaha won't start
Optional Information: Year: 2007Make (other): YamahaModel: GrizzlyEngine: 700 Fi Already Tried: ATV just had a full tune up less than 2 months ago--oil change, etc. No heavy use since. Full fuel tank also. Was running fine & I have no idea what happened. It will not start. ATV will turn over, but not start. All sounds normal, no warning lights, no symptoms prior to problem. If it does actually start (1 in maybe 10 tries) it will only run 2-3 seconds before dying. Giving it more gas on the throttle has no effect. thanks
Yes, there is too much fuel in the carb. You can also let it sit for about 15 minutes and try again.
It's been sitting for two weeks. No go. No change. Any other ideas?
check the engine oil level and plug wire (coil) pull out the plug and clean it....
I checked the oil--Looks good. I don't know what you mean about the plug wire, so I didn't do anything about that part of your advice. I wouldn't expect their to be a problem with the oil though, like I said, the oil was changed very recently. After resting for over a week, it still won't start. It is acting like it is flooded, but it's acting this way from the very 1st attempt, so that doesn't make much sense to me. Thanks if anyone has any other thoughts.
thats why i told you to clean the carb.... Otherwise its ok no problem thanks.
k. I'll clean the carb & let you know what happens.
sprayed carb cleaner & there was no change. took out air filter & checked hoses. all look clean & dry. there are only 500 hours on this ATV. no hard use.
Hi and welcome to JustAnswer,If it is a 2007 Yamaha Grizzly 700 FI, then it would be fuel injected. On a 'no start' problem, initial checks would be to determine if it is an electrical problem or fuel related issue. Remove the sparkplug, re-attach it to sparkplug wire and lay it against any metal. Determine if there is spark while starting:
Thanks Benimur! The machine is indeed a 2007 Yamaha Grizzly 700 FI. There is a spark and there is a noticable smell of fuel. Thanks for your efforts.
Initially, dry the inside of the combustion chamber through the sparkplug hole. Spray the inside with a can of compressed air and crank the engine with no sparkplug. Try again. If still a no-go, then based on no warning lights and the presence of spark as well as fuel possibilities are:

Benimur, When I took the spark plug out the other day to check it, I noticed the end of it was pretty dark/dirty looking. I went ahead and bought a new spark plug to replace it. Presto! She started right up! It still seems odd to me that they didn't check this when I had the mechanics do oil change and everything else last month. But she's up and running now regardless. How long are spark plugs supposed to last? I've not taken it for a test drive, but maybe I can do that today. Thanks Benimur, for having me look at the spark plug to begin with.
Interesting, as the sparkplug would normally be the first to be checked and/or replaced. This is because the condition of the sparkplug tip would already be indicative of so many aspects on the engine's performance. This chart may interest you. Sparkplug would be good for several thousand kilometers depending on use, quality of fuel and condition of the engine.Glad that the Grizzly is now running. Ride Safe.
hmmm... Several thousand kilometers huh? I only have 500 miles on this machine. I hope the fouled spark plug is not a sign of other issues...
AHH just clicked the link to the chart. That is helpful! Tks again.
here's another chart: http://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html
Apppreciate the link to the other reference.500 miles and fouled plugs, you may want to confer back with the shop that did the maintenance/full tune-up..
