So my rzr has been acting up, we’ve done just about everything but check wiring harness and the ecu. Have anyone had any problems with these. It will crank up perfectly fine and then you press the gas and it dies out. I just don’t see those 2 things being the reason that it’s doing that.

You haven’t given us much, have you checked the fuel filter, fuel pressure , and the throttle position sensor ?

It will idle perfectly fun but when you give it gas it dies Here’s what I’ve checked so far
Check valves
Check timing
Check fuel pressure at rail
Check fuel pressure at pump
Replace spark plugs and set at proper gap
Check grounds
Cleaned intake plenum
Swapped coil
Swapped map sensor
Swapped crank position sensor
Cleaned throttle body
Checked compression
Checked voltage to fuel pump while running
Fixed loose wires on fuse box.
Checked to make sure fuel filter was clean.

I'm assuming you drained all the gas and used fresh? Or run some Ethanol Free through it?
Looks like you have done a lot of stuff. That is an odd problem. Worst case take it to your local Polaris Stealership.
