2018 Polaris RZR On Ebay

We have been having all kinds of fuel issues with this ranger.  When you try to start it when it is cold outside, it does not want to start.  It will crank over fine but doesn't start but if you stop and come back 10 minutes later or so, it will start up.  But even then, it is idling real bad.  Usually will die a few times before you can get going, really have to feather the gas pedal to keep it alive.  Once it gets warmed up, it does start better but something still not right.  Even when it is warm outside, it will start up but just doesn't idle right.
I bought a fuel pump kit, not the whole assembly, just the pump and replaced that and the same thing happens.  I am in the process of trying to check the fuel pressure on it but the fuel pressure gauge I got from our local auto parts store seems to be defective.  Had it hooked up and can't get the gauge to show any pressure at all yet it will still start up.   If it does have the correct pressure, what would be the next place to start looking at?  If it doesn't have correct pressure, is there something else on the assembly that would cause low pressure?  We checked the voltage on the connecter and one gets 12 volts for just a few seconds and the other one gets 4.9 volts.  The other 2 show nothing.  I am guessing the one with 4.9 volts is for the fuel gauge sender and the one that has 12 volts is the pump.   When you take the fuel line off on the engine side and turn the key on, how far should it throw fuel out?  
We have taken it to 2 shops and neither one was able to do anything with it, one said there was nothing wrong.  Not sure if they really did any checking or what or they just don't know what to do with it.  
Would the whole fuel pump assembly out of a ranger 570 work with the ranger 800?  Would I be able to swap them without any issues?  To buy a whole new assembly, it's around $400, don't really want to spend that much not knowing if it will fix it or not.

So, im new to UTV's always ridden ATV's typically the Polaris 850's and such and a few Rubicon's. Moved into the county with some land and figured I'd get back into the country mud. I've been doing some research on UTV's and I am impressed, I went to the local pony powersports and sat in a few atvs, being 6ft1 and 360lbs I wanted to make sure I could fit into one of them comfortably before doing my research on which one I wanted. My conclusion was - the Honda Pioneer 1000 limited edition , or the Polaris ranger xp 1000 (would prefer the highlander edition).  I was trying to do some research on which one is better, I know they are both leaders in the industry from the research I have done.  I'll mostly be driving through creeks taking it to some trails and moving some things here and there (firewood, fallen trees, ect.) the years im considering are 2017,2018 and if there is a big enough change in the model that a 2019 would make more sense then I would do that. Looking to spend 20k ish. Any help on deciding the better of the rangers and pioneers would be appreciated, or if you have another UTV a bigger guy should look into!
