My 2014 570 won't start. I started it yesterday and pulled it out of the shop. 30 minutes later I tried to start it and it won't turn over. Battery is good. I ran it for about 30 minutes the day before. Bought it in June of 2014. Any suggestions?

Do the lights (etc...) work? If the rest of the electrical system seems to be functioning properly, I'd suspect the brake interlock switch (the switch that makes you press the brake pedal in order to start it). Try pressing the brake pedal repeatedly and harder. You might have to locate the switch and clean the connector. You can also bypass that switch with a jumper wire to see if it's the problem.

Also, several members have reported that their dealers did not correctly tighten the battery cables properly - might want to check those (and all other electrical connections you can find).

Have you checked all of the fuses? Not only make sure that they're good, but also are seated well in the socket.

Fuses are good. It finally did turn over then it sputtered out. I tried it after that and sputtered out again. Any other suggestions and thank y'all for everything so far. Would like to get it running and not have to take it in, long wait at dealership.

Pulling plug is next step. How do I go about checking if fuel is being delivered?
I would have to play around with it as I'm new to Polaris, but you might consider googling fuel pressure or fuel delivery on Polaris Ranger or RZR. I thought of it because when you turn the key on, you can hear what appears to me the fuel pump/pressure or something of that nature for about 2-3 seconds which appears to prepare for start. I'm assuming the unit is turning over? If completely dead then I would be looking at all electrical connections including ECU, ground wires, battery, etc. How about listing everything you have tried?

I took a minute to read over your post again and the piece you mention "it won't turn over" and in a later one it sputtered leads me to believe you have a loose wire/bad connection somewhere on the unit. Check the ground wire from the battery to frame.

Kinda light on the details - when you say it won't 'turn over,' what exactly do you mean? The engine doesn't turn or the engine spins but does not start? If the engine doesn't spin, then a likely culprit is the battery. It may start one day and do nothing the next just from the surface charge. When it doesn't start, how many volts does it show? If it's below about 12.1, put it on a charger over night. The next day, turn your headlights on (not the engine) for a minute or two to burn off the surface charge and measure your battery voltage again. If it's not 12.6/7, take the battery to an auto parts store and have it load tested - generally a free service. If it is fully charged, turn your key to the on position (not to 'start') - you should hear your fuel pump clicking. If not, check your electrical connections again including both the fuel pump and ECU relays in your fuse box. All the relays are the same so try switching them around. If you do hear the 'clicking,' before starting the engine but the engine still does not start, check your fuel tank vent line for obstructions then perform a pressure check on your fuel line. Not sure what PSI your fuel pump should deliver - if no one chimes in with that figure, call you dealer's service department; they should tell you over the phone. If your fuel pump does not deliver the correct PSI, replace the fuel pump.

I doubt that your fuel is bad since it ran fine one day but not the next but you could have gotten dirt or water into your fuel tank - usually through the vent line. Did you hose down your machine between the day it ran OK and the day it didn't? A fairly common occurrence is for folks to squirt water into the fuel tank through the vent line and not realize it - it's kind of hidden. If that is a possibility, then drain (siphon) your fuel tank and put in fresh gas. Cycle your fuel pump 6 times (turn the key on but not to 'start') before trying to start it. Also check for dirt in the bottom of the tank while it is empty. Dirt can be introduced into the fuel tank via the vent line as well, especially if you went through mud. If you do see dirt in the bottom of the tank, remove the fuel pump and check the filter sock for signs of dirt.

There is a slim chance your fuel could be bad. How 'old' is that tank of gas? How often do you run your machine? Try that stuff and let us know how you make out - or take it to the dealer and have them run their Digital Wrench diagnostics on it.

My shipment of my replacement spark plug finally came in (small town problems). I got it changed out and battery fully charged and it started up. Thanks for everyone's suggestions and help. Have a great day.

It really sounds like your battery is on its way out. Stock ones just don't seem to last very long. I'd be looking to upgrade before it strands ya somewhere.

I upgraded it just recently to the Odyssey PC925. Battery was low due to running the radio too long:) It was the spark plug all along. Just took a while to find a replacement. All is good now. Thanks.

Son in laws ranger won’t start. Pulled the plug to the fuel pump and measured the voltage, has 12vdc but only for a couple of seconds and the power never comes back unless to turn the key off and then back on. I can hear the relay come on and then drop out. This is without the fuel pump unplugged. When it wouldn’t start I could never hear the pump running with it plugged up. Any suggestions?
