FREE and EASY TRICK for Tough STARTING Yamaha Phazers

Here is a trick to get a cold engine started, especially with a low battery or slow turning starter.
This trick is extremely effective with the early model Phazers that had version -00 ECUs that exacerbated the starting problem
But this trick will work with Phazer, Nytro, Venture and other models using the same guage pod. (Note that you would prime through Diagnostic mode 36,37, AND 38 for the 3 cyl models)

[@brettlarson4327]

UPDATE: In cold weather I am finding that it takes between 4 and 7 cylces (presses of the handwarmer button) PER cylinder to adequately prime the engine. Apparently each cycle does not put much fuel into the engine and I have not yet had any trouble with flooding the motor. And also this priming technique could come in handy for any engine cranking slow, for very cold starts, and also for rope starts where you want it to pop off on the first pull.

thanks man

[@brennonraser8851]

Damn… I just got an 07 and it’s not an easy starter here in MN… tried this and it fired right up.. I owe you a beer!!!!!

[@brettlarson4327]

Cool! Hey yeah always have a can of spray start handy too for those "cold-cold" days though. I find this trick handy, but my sled has it's temp limits on it working. At some point ether is the only way mine will start.

[@brianfedor8393]

Thank you for the great tip! I've always had problems starting my sled even after new battery, plugs and cleaning! Scrappy dealers never mentioned a recall. Worked perfectly!

[@brettlarson4327]

Glad it worked! But I have found there are days... when it is "extra-special" cold... or the batt is weak, where you need a shot of starting fluid down the intake tubes.

[@slode1693]

You can save a step by going to diagnostic mode 50, that is for the full system and primes all 2 or 3 injectors at the same time.

[@brettlarson4327]

Cool! 👍👍 I missed that mode when looking through it.

[@targabill]

In the manual, #36 & #37 cycles the actual injector, #50 cycles a "Fuel Injection System Relay"... Does this accomplish the same by adding fuel into each intake manifold?? I believe the System Relay operates the Fuel Pump which cycles fuel but doesn't open the injectors???

[@brettlarson4327]

One other tip I found that helps is to make a straight crank attempt at first (as seen in video) and then do this priming trick for the next try if needed.

[@666dynomax]

Really wish these weren’t such a pig starting. I run full synthetic not sure if that does anything

[@TrailRat700xc]

Thanks for all the info Brett👍

[@Qwartle]

Dude, You are the man! I haven't encountered this problem, but it's good to know. Also thanks for the info on the diag mode

[@brettlarson4327]

Yeah I love Yamaha for allowing the user all the functions in diag mode! You can do a lot of things in there and I remembered that you could cycle the injectors.. which gave me the idea to try this.

[@andylarson3547]

Cool hack. Apparently these phazers do not like old gas. Had 07 that would not start. Needed fresh fuel and spark plugs started right up.

[@garykusnierz2108]

Thank you that was a great help ! Gary K

[@user-tt6eo8jw8i]

Had to prime 4 times per cylinder to get mine going today (-15 C)

[@Rollie-Lund]

I will have to try this on my 09, it starts crappy, with a fairly new battery in it.

[@nathannaab8560]

Great tip! Thank you

[@tylerstickel5137]

Very nice

[@user-sh5xc1wu5t]

Thanks, it really works! but how to fix the problem? My snowmobile doesn't start well even when it's warm.

[@brettlarson4327]

It might be time for a valve adjustment if you are having trouble with warm starts.

[@someguy325es]

thank you!

[@mikehawk4665]

great vid thanks for that info my 2012 nytro does start fine but the check engine light flashes when i come to a stop but once i take of its fine was wondering if you heard of this before thank you

[@brettlarson4327]

Yeah that check light should have a code with it that you can read if you follow the service manual instructions. That will give a good clue as to where to start.

[@mikehawk4665]

@@brettlarson4327 ok great thank you !

[@traviskat7068]

Would this the same procedure on a Nytro?

[@brettlarson4327]

Yes it would. Same diag mode

[@traviskat7068]

Thank you sir, great video btw

[@eco_guardian]

I just bought 2 of these and I am regretting it. They are both hard to start and regularly kill the battery trying to start them. Since they don't have pull starters, you have to have jumper cables, the right hex driver to get to the battery and a willing 2nd snowmobile. Very disappointed with yamaha. I will try this tip though, thanks.

[@TaraDantouze]

did you try heating the engine with a blow dryer or little buddy heater?

[@jasonberning1086]

These are great sleds! Sounds like you have an issue going on. They should fire right up. Maybe try running a heavy dose of Seafoam through fuel tank to clean fuel injectors. Should also only be running premium fuel

[@eco_guardian]

@@jasonberning1086 I've done seafoam, replaced batteries, new plugs, new fuel, they just can't turn fast enough in weather below -10. Now the problem is rolling them over. I have never rolled a sled so often. Everyone of my friends who drive them roll them. Super dangerous.

[@theofarrell2918]

Not sure if I’m a bit late. But I’d it the same number for a Yamaha venture sled too. Cant find info about it online. Are all Yamahas the same?

[@theofarrell2918]

Tried today but when I go into them diagnostics menu I just hear the fuel pump going. When I go to 36 and 37 and press the hand warmer button nothing happens. No light or engine light comes on. The yellow warning light is on and isn’t usually on so maybe that’s the problem.

[@isozero7265]

TY :-)

[@brettlarson4327]

Haha yeah I'm not claiming that I invented this method, but in this case I did come up with it on my own and not with help (like usual) from TY. And since I didn't see a good vid on it I figured I'd shoot one quick ;)

[@melkerlarsson5728]

Or just turn the key one step and when it has stop buzzing turn off the key and do that again 3times. I

[@brettlarson4327]

Nope what you speak of only pressurizes the fuel rail but does not pump any fuel into the engine. The method in this video actually cycles the injectors and "sprays" a bit of that pressurized fuel rail fuel in.

[@bob57786]

Where do you spay the starting fluid?

[@brettlarson4327]

Pop off the airbox lid on the front nose cone and spray a shot down each velocity tube leading to the throttle bodies

[@1957brun]

Have you ever had a problem with the reverse that doesn't want to board 2 out of 3 times. thank you

[@brettlarson4327]

My reverse has been good so far but people say to bounce on the running boards when trying to go to reverse... helps take gear pressure off momentarily and allows the shift.

[@1957brun]

@@brettlarson4327 I say that because I have a venture mp 2015 and I am told to clean the electrical mechanism but I am not born where? Thank you from Québec Canada.

[@brettlarson4327]

@@1957brun I dont think it is the electrical connector if it is working intermittently.

[@1957brun]

@@brettlarson4327 thank you Brett.

[@jasonberning1086]

Yes, rock the sled forward and back by lunging your body/pulling on the handle bars etc. and it should go right into reverse

[@666dynomax]

Anyone ever try a dual battery setup????

[@joerutkowsky3261]

Would this work on the nytro

[@brettlarson4327]

Yes it will. But there is one more diag mode (near 36) for the third cyl.
