2006 Polraris Sportsman 500

Replaced starter, starter solenoid and Bendix cause the old girl wouldn't start. While I had the some of the plastic off I replaced the fuel filter. Turned the key Saturday morning and if fired right up. Rode it around  the place and just let it run for awhile. Multiple times that day I would just go hit the key and it started like nobody's  business. Went out Sunday for a ride and all it does is turn over and not start. Just turns over like it's out of gas. Put fresh gas in it on Saturday. Battery has been on a tender and  reads 12.87 on the meter. WTH? Any ideas?

Carburetor jet is my guess.

I assume it’s Carbureted? Give that a good cleaning.

Fuel pump after that? When u turn your key one position over can you hear it pumping fuel?

Batt voltage seems ok but I would start there.  Increase voltages.  Check coil wires n plug wire for breaks.  So check for spark first thing!  Stator issue?  Volt reg.?  Also things like faulty fuel tank cap vent?  Pinched fuel line?  Pull plug, does it smell of heavy gas?  Start at plug..

Turn off or bypass the kill switch, sounds to me like a wire came unplugged or the switch went bad !

My quad did the exact same thing a couple of years ago. A chunk of rust from the inside of the fuel tank cap jammed up the jet carb.  There is no fuel filter on my Yamaha Kodiak so that's how the mechanic said it got by.  If yours sat for a long time it might be gummed up fuel also.

It turns over (I’m assuming it turns over vigorously) – so it isn’t the battery.   

To start a motor needs
1.   Fuel
2.   Air
3.   Ignition source

I’d start with #3 – check for spark at the plug.  See what you find then reassess

It's fuel injected, no carb. After sitting all night and day on the battery tender I have next to 13 volts tonight. Pulled the outlet fuel line off the filter and there's fuel there. However the volume of fuel did not increase while I was hitting the key turning it over??  With everything working as it should, shouldn't the fuel been shooting out of the filter?

Here's the thing. I rode it onto the garage, shut it off, left it overnight and it would not start again. Looked for a wire that may have come loose, etc.

Dummie disclaimer....how do I check for spark??

Thank

Fuel pump and injectors to check since no carb.

Pull the fuel line off of where it enters the fuel filter. Turn the key. Should push a good amount of pressurized fuel out the line. Should also just be able to hear the fuel pump engage when you turn the key before you start it. (Buzz sound) If you do end up replacing the fuel pump, it’s a piece of cake. I just did one on an 06 700 efi.

I’d double/triple check all wiring. A high % of EFI engine issues are electrical.

Wolfdog I'll try that tomorrow night.

Thanks

I checked and it has spark. Does this rule out the starting system?

I would check the throttle ETC cable adjustment, there may be too much slack and might need to be adjusted-tightened.  If you try to start with thumb pressure on the throttle lever and starts and runs,  but then dies when released that could be the issue.

Bringing this back up.....

Finally got back to working on this. Here's the story.

Installed a brand new starter, Bendix and solenoid. Fired right up after installing those three items, rode around the property. Washed it, rode some more. Started throughout the day like it should. Parked it in the garage. Go out later for a ride it will not start. Just cranks and cranks. Checked for spark. Yep, it's there. Installed new fuel filter and pulled the line off and turned it over. Plenty of gas flowing. Have checked multiple times for any plugs, wires, cables, etc. which may have come undone. Just this morning I installed new spark plug and (not cheap) battery. Still just cranks like a bandit but will not light up.

So pissed right now I'd like to put a bullet in it. Dealer or local shop (Pro-Caliber) will just be an exercise in frustration. What am I missing?? The wrench icon (service) illuminates on the speedo while it's cranking but I can't remember if it should and that if it goes away once the motor starts?

Likely just a bulb check.
