2010 Vector fuel pump relay

I just bought a used 2010 Vector GT. It started up fine and ran for a few minutes in 0F temp and then I shut it off, 15 minutes later it would crank but not start, code 43 was showing. Called dealer and they told me to replace the fuel pump relay with an updated one, cost was around 13 dollars. Everything seems to be fine now. Just though I would pass this along. This happen to me after travelling 1000Km to ride, lucky it was an easy fix.

Northern Rider also posted that he purchased a new "RED" relay from Yamaha prior to his trip in Quebec and said not once did he have an issue in -26c weather.

Also, from what you say above, just starting them for a few minutes before shutting them off is not good as they should run at least 10-15 minutes before being shut down or you risk the fouling of your plugs.

what's the part number ?

The most up to date part number for the fuel pump relay is 8HG-81950-09-00 which gets you both the relay (8HG-81951-00-00) and the relay holder (8HG-81952-00-00) . This style relay was introduced on the 2011 models and does not have the tabs on the side of it that lock it into the holder - this is to make it easier to install and remove the relay - the relay still stays in place as the male/female terminals are enough to securely hold it in. FYI - this style relay has had better success than the previous styles but still can have issues after being used in heavy snow conditions and then subjected to sub zero temperatures so the search for the perfect relay continues but this one is the best currently offered.

Just for the heck of it I took my old relay and drilled a couple of holes in it and filled it with WD-40, wiped it clean and siliconed the holes so it is sealed. I have been running with it for a few days now with no issues. There shouldn't be any moisture in it now to freeze up. I will keep my new one with me just in case.

Having learned about WD and it's magic with electrical connections,etc. 30 years ago I have used it since on all motor electrical componants,etc. With these snowmachines I spray them all the time during the season. Spray every connection,ground,etc. Never had an electrical problem on my marine outboards,home tractors,trucks,etc.
