Polaris ranger 800 was running then just killed won't starts spins over


Hey Timothy,
First, make sure the kill switch is not on "kill"
An internal combustion engine needs three things to run:
1. A properly timed spark - 2. delivery of a proper air/fuel ratio - 3. adequate compression >120PSI. (make sure air filter is clean and treated)
NOW -
1. Install a new, correct, spark plug. - MAKE SURE it firing.
2. Make sure you are getting fuel to the carburetor.
3. Make sure you are getting fuel THROUGH the carburetor.
4. Make sure you have compression. 120psi+

One (or more) of these 3 requirements is NOT happening.. eliminate one at a time!!

My 2005 polaris ranger 500 shuts off . let it rest 30 minutes and it runs. what can i do


Next time you are riding and it cuts off.. BE PREPARED to remove the spark plug ASAP... and see if its firing.. (you could have a new one ready to use for a check!!!!)..if its not firing.. its an electrical issue...(coil).. ..if it is firing.. check your fuel system for blockage... YOU may need a pro for this.... sorry...

2007 Polaris phoenix 200, has new fuel cleaned carb,good blue spark,fires don't start or run,plug lil wet but not flooded or soaked


If you have spark at the right time, fuel, air.... you might try a spray of staring fluid. I would then check the compression. If it is too low it will not start.

89 Polaris Ranger500 6x6 side by sideis coughing,spitting and backfireing thew carb.whats the fix


I would start by pulling and cleaning the carb, air filter and spark plug. Usually the cause starts with dirty air filters that gets the carbs dirty which then cause the polaris to run rich and the plug will start to foul. The unburnt fuel ignites at the wrong time and back fires. A less likely problem would be out of timing.

What causes my Polaris ranger to backfire when starting?


Badly adjusted ignition timing. It is firing too far advanced before TDC (top dead centre of piston stroke) if backfiring through the carb, or too far retarded if firing through the exhaust.

Can the charging system on a 2004 polaris ranger cause back firing cutting out and dying


these ATVs do a lot of hard work for size of motor

worth checking other things as per normal servicing
new spark plug
clean air filter
drain and add new fuel to tank
wont hurt to clean the carby or bowl contents
if fitted with a fuel filter inline .. fit a new one

and valves adjustment if still back firing

My 2007 450 sportsman won.t start but she backfires


Remove the seat, and take the cover off the air filter container. Place your hand over the end to aid in fuel flow to the carburator. You might not be getting enough fuel which is causing it to backfire and not start completely.
Attempt to start the ATV once you get fuel flowing you should be all set. Clean that filter as well.
