I just bought my first RZR, it is a 2015 RZR s 900. It was not running but I thought it to be an easy fix. The problem I am having is no pulse to the left injector, as I confirmed with a noid light. Bought a new ECU off ebay and that did not fix it. Checking wires now. It is not the injector harness as I have cut that off to test wires down to the ECU. I have tested a signal from the pin in the harness from the ECU (green wire) to the injector end and that is good. the blue wire goes to a bundle of red/blue wires and not sure were they all go.
What should I do next or what all can cause the left injector only not to get a pulse?
If the other one pulses and they both have 12 volts, it has to be the ECU or the wire from that one to the ECU. I would run a new wire if the harness is that hard to test. A wiring diagram would help too of course.
if he uses a noid light it's not the injector. If the injector coil is open then the voltage wont go thru the injector so to speak so you wont get a pulse. Swapping injectors would be a good test for that, or simply checking for an open circuit across the injector itself.
If you don't have a noid light you can hook a test light to battery positive and probe the wire to the ECU and see if it blinks while cranking/running.
It should have 12 volts to both injectors on one side when cranking/running too.

I just figured for all of you guys doing your own tuning I would give you some help. The Powervision 3 tuner has a lot of complex strategy and can be overwhelming unless you have good comprehension of how it all works. I will try to check in from time to time and answer questions you may have or...
