Found the problem. I tried to start it again, and watched where the fire(literally) from the backfire was at, turns out it was on the front of the engine, not the back, so I removed the air filter box again and checked, turns out the throttle bodies had been knocked completely off of the...

The backstory. Son was riding, hit a stump which pitched the machine into a fence post, laying on its left side, Front bumper took most of the abuse. No one hurt, no apparent damage except for the bumper. Never lost oil pressure, didn't need to prime the oil pump as usual. Went to start it...

See my post a few days ago with a similar issue. After the machine has sat unused for a long period, it runs great for a few starts, but when shut off, one or both injectors will stick shut. I did find a way to clean them. When running the diagnostics, the clicking sound is very quiet, but...

Just had those off when I had it apart to remove the injectors, everything looked fine, no improvement before or after .

Kids ( it is their machine) took it for a ride today, idled fine the whole time.

Upping the idle with the screw was the first thing I tried. Didn't make any difference. I need to rev it 2500 to keep it running at all. Then the next ride, it idles fine down at 1800, regardless of temperature or electrical load. I also observed the TPS reading with the onboard diagnostics...

2015 Phazer, very low miles, randomly stalls when the throttle is released. Need to give it some throttle to keep it running. Won't restart until giving it some throttle. Seems to start fine the first time cold, revs up to 2400ish while warming up, idles down to 1800ish as it warms up. Runs...

Might have mine figured out. Put battery charger on and it started right away. Doesn't really explain why it would start at 20 below and cold engine, but not warmer with a warm engine though. Had tried bat charger right away, but didn't realize charger wasn't working ( 2 of them quit at once...

My machine had new sat new unused for over 2 years before we bought it. It ran fine for a few days before the injectors stuck. Dealer didn't believe me, and took a long time to diagnose it before finally acknowledging the problem. They tried to blame dirty gas which didn't make any sense...

I had this issue last year on a week old machine. Check if you are getting fuel to the injectors, and if so, pull the injectors, reconnect and see if they are spraying when cranking. In my case, both injectors had seized closed. Blast of air in the tip from the a blow gun was enough to unseat...

I'm having a similar problem with my boy's new M-TX. I'm almost scared to ride it, it darts so bad and nearly tips every time it darts. 50km/h is way too fast the way it darts. Being the mountain machine, it has the wide skis with very deep keels( is that the word?) On hard pack, or deep...

Dealer couldn't look at it for more than a week. But it is there now. Kids will have to wait.

Have Spark, have fuel at fuel rail, but no fuel coming from injectors. No codes showing. Where to now?

No codes show up, is there any reason to go into the diagnostics mode when there are no code indicated?

Pump is pumping, installed new plugs, and still no start. Apparently fouled plugs were not the problem. Where do I look now, besides, warranty? Have it warming up, just in case it is an ice issue.

And thank you for the advice. I did just that too.

Managed to remove the relay, verified by wiring diagram that the red one is the fuel pump relay. checked with voltmeter, when the key is turned on, the signal wire has power for a few seconds like it should, but the red/blue to the fuel pump doesn't. So I swapped with the next relay, standard...

Hello all, I'm new to the forum, and new to Yamaha four strokes. We got my boys a new, but 2015 model year phazer MTX. I realize the fuel pump relay issue has been beat to death on here, but I think this is something different. Was running great for a few rides. But as of today when I turn...
