2015 Arctic Cat ZR 6000 RR Snowmobile Won’t Start

2015 Arctic Cat ZR 6000 RR Snowmobile Won’t Start
  • The ‘snowmobile won’t start’ information herein is specific to all 2015 Arctic Cat 2-stroke sleds, including ZR, XF, M, 4000, 6000 and 8000 models.

There are two types of snowmobiles in this world; sleds that start and snow machines that will not activate and begin to work. A snowmobile internal-combustion engine needs a few things to turn on and begin operating, mainly spark, fuel and air. If one of these things are missing the sled’s engine will not fire up and start running. The good news: A troubleshooting guide was published by the manufacturer that list all of the reasons why the engine does not start. The guide is meant to show the troubleshooter a way to trace and correct faults within a snowmobile electronic or mechanical system.

Charging System

Snowmobiling is seasonal, so sleds often sit in storage for long periods of time, and batteries often lose their charge as they sit. Before using this troubleshooting guide, check the charging system and make sure it’s delivering electrical power to your vehicle. If the starter does not turn, check the following conditions:

  1. Battery discharged. Check and charge battery if required.
  2. Loose electrical connection. Inspect tightness on all wiring connections.
  3. Grounding improper. Check ground connections.
  4. Fuse blown or not installed. Check and replace fuse if required.
  5. Faulty starter (electric start models). Bench test starter.

No Spark at Spark Plugs

If an electric spark does not occur at the spark plug, the compressed mixture of fuel and air will not ignite the explosive mixture and cause the engine to begin to work. It means there is something wrong with the ignition system. The ignition system includes the spark plugs, ignition timing sensor, stator, wiring harness, emergency stop switch and other associated parts like high tension leads or spark-plug caps. If the snowmobile won’t start because of an absence of spark at the spark plugs, check the following conditions and its remedy.

Diagnose a Snowmobile with Weak or no Spark

For reference, a weak plug can produce spark in open air but will not under compression.

No Fuel at Cylinders

When your snowmobile won’t start, chances are it is not getting the refined petroleum it needs for the internal-combustion engine to fire up and start operating. In other words, no fuel is reaching the cylinder. It could be a simple issue like a fuel injector stuck closed, faulty fuel pump, fuel pressure regulator or clogged fuel filter. If you don’t see fuel in the cylinders spray the intake with a little staring fluid while someone cranks it. Anyhow, if the engine is not getting fuel to the cylinder check the following conditions and its remedy.

How can I tell if the engine is getting fuel when it doesn't start?

Fuel Does Not Ignite

If you’ve made it this far, it means you’ve already established that the spark plugs have sufficient spark and fuel at the cylinder. When an engine has spark and sufficient fuel, the problem is either primary or secondary low compression, sensor malfunction or even contaminated fuel or too much fuel. If the fuel doesn’t not ignite, check the following conditions and its remedy.

Engine cranks but won't start, it has spark and gasoline.

A snowmobile is a motor vehicle or sled with caterpillar tracks on the rear and ski like runners in the front. It’s designed for traveling over snow. But unlike early snowmobile carburetor models, modern electronic fuel injection snowmobiles have a lot more components that can malfunction and prevent the snowmobile from turning on and start to run. Use the above troubleshooting guide, it list the most probable causes to help you pinpoint the problem and its solution.
