4 wheeler won't turn over

Alright outdoor baws. I have a 2012 Polaris sportsman 800. Went to tower trax awhile back. Ended up going into a hole and making a large wave. Ended up stalling out mid way.
Pulled the bike out, didn't try to start it. Tilted it up to make sure no water was in the exhaust. Has not started sense. I changed the plugs, made sure I have spark. Drained the fuel tank and replaced the injectors. Still won't start. I smell fuel when I turn it over but it won't fire up.

if it were carbed I would say the cylinder is full of gas and the oil will be mixed with it.
but since its fuel injected it must be a kill switch somewhere not letting it start.
check the neutral switch and fuses
do you have spark at the plugs?

It won't TURN over? Or it won't FIRE up?
I'm not trying to be a dick, but your title says one thing and the last line of the post says another.

Unplug anything that got wet. Get some blue shower or tun-o-wash or the equivalent and spray connections and let dry or flash off. Put dielectric grease and reseat the plug. Depending on how long it set coorosion may have taken hold in some of the molex style connectors.
I like those two sprays as they won't dissolve plastic. Blue shower is not as aggressive.
Look for any fuses that may have opened up.

Can you push start it?
The starter isn't cranking?
Three things, spark, fuel compression. You have those three and it'll run.
You say you have spark on ignition?
You are getting fuel spray into the cylinders?
We are assuming there is no mechanical block issue and that the internals are working.
Saying you got spark it has to be fuel.
Try starter fluid and see if it starts.
Others said kill switches and fuses, check all that.
Injector engines are actually easier to diagnose because you don't have umpteen carb issues that can arise.

Water in the fuel tank, since water is heavier than fuel it settles to the bottom. If this is the case you will probably need to put a new fuel pump, filter, and either clean or replace the injectors again.

I pulled the plugs out. Placed my finger over each cylinder to create a vacuum and see if any water would come out. None did. I put new plugs in. Before I put them in, I turned on the ignition and saw spark in each plug. I then placed the plugs back in the engine.
I received an error code 51 and 52. Guides show that as being injectors. I purchased two new injectors. Since I had the fuel tank off. I dumped it. Put the new injectors in, put fresh fuel in.
Go to start it and the engine is turning, but it is not starting. I can smell fuel. So the fuel
Pump must be working.

Same thing I was thinking. Bought a weed eater off of somebody who didn't know what they was talking about too.

I think you could read it and figure out what was meant.

Hell mine has only turned over once and was a pita to get back upright, not sure I would ever do it on putpose.
On a more serious note, if you are getting both spark and fuel which you claim (and I doubt) on a EFI engine there is only one culprit left, pull the air filter and give it a shot.

Air box is open and clean. If I am seeing spark from the plugs when I attemp to start it with the plugs attached to the wires and not placed inside the cylinder then I'm getting spark. I can hear the fuel pump running and I can smell fuel.

I don't know anything about a Polaris,but can they jump time?
If you are getting fuel/air in the cylinders,and you have a spark,it should at least be trying to start,unless you have a stuck valve(s) or timing is off.
I guess it could also be an air mixture problem too,but it seems like it would at least try to fire if that were the problem.

I honestly would try to spray a touch of ether or a few drops of gas in the plug hole, replace plug and give it a shot. If this does not work it may be time to seek professional help. If it was not CVT I would try to pull it off for a bit.
perhaps not enough battery voltage, try starting it with jumper cables attached.

Either it's something very simple getting overlooked, or something very complicated that you need a professional for. Fire+fuel should be doing something.

Although you said you get a spark...what color is the spark? It may be a week spark due to a issue with the coil. If it's blue...you're good.

I thought it was blue, but I could be wrong, I'll check again today.

Spoke to ATV Zone, they believe it just needs a reflash. So I will bring it up to them this week to see what happens.
