I have a RZR of similar vintage, I don't think the ECU is involved with the fuel pump power. Are you sure you checked all the fuses? I'm pretty sure the fuel pump is powered by key on power. It's probably worth the cost of a service manual to get the wiring diagram to verify. Also don't forget to check grounds.

 

Okay I will check it thanks

 

We have a service manual available. Please email us and we will send you a copy.

In 2015 rangers (gas) were made up to 900xp.
the 1000 was either deisel or RZR.

say it is 900....

Forcing 12v through the pump seem to work but are you getting the correct resistance throught the pump?

Pin 3 is your battery positive.
it goes to the fuse/relay.
I would check all relays (they can be tested) and all fuses.

Pin 4 is your frame ground.
That ground connector to frame has 8 wires. I would make sure that connection is clean and or no broken wires.

Good luck!

 

@valley thanks

 

I'm having the same exact problem. How did you solve the problem?

 

I haven't yet. I sent my ECU off to have it checked and it's good.

 

These Polaris fuel pump/electrical issues multiple times on my 2016 ranger xp 900 have just about frustrated me up to maybe it is time to go to Honda's SBS. Too many electrical issues with Polaris
