Polaris Ranger 800 crew injectors will not fire

I have checked everything on my Ranger and it has been narrowed down to the injectors not firing. It is at the shop now and the mechanic is stumped. Any suggestions?

Can the ECU see the reluctor ring? If not it won't know when to fire.. so check the sensor and it's wiring, I've seen them rub through just near the multiplug as polaris often cable ties it too tightly and the 800 vibrates so much the constant movement cuts into the wiring.

The injector wiring can also break at the very top as it goes into the injector itself, they normally develop a misfire first though.

Just pop them out and crank it over to check if they are spraying and broken wire should set a code
