2021 800 zforce won't start
« on: September 04, 2021, 11:29:25 AM »
Hey guys, new member here. Maybe this has already been discussed but I didn't find anything. I have a 2021 zforce 800 trail SxS. I trailered out to Idaho and ran my unit around the first day no issues. Parked it in the garage second day it wouldn't start in the morning. All of the sudden it started and no issues all day. The next day same issue once I got it started it ran and started all day. This morning is did it again. Here is what is happening. I have it in park and I put my foot on the brake it is full of gas the lights work the fuel pump runs but the starter won't engage. Nothing happens when I turn the key. I thought it was the gear shifter to I tried to jiggle that, tried to start it in neutral or park, nothing. We turned the heat on in the garage this morning thinking if we warmed it up it might start. Still nothing. I called the dealer yesterday and they suggested fuses or low battery. But this is not it since it has happened two days in a row and then all of the sudden the starter works when you turn the key and it works all day long. Then the next morning it does the same thing all over again. I have good quality gas in it. It only has about 350 miles on it. Has anyone else had this problem? Where do I start? Thanks for any help guys!

Welcome. Sounds like something with either the interloc system..the system that allows it to start when either the brake is depressed or the neutral or park light is on in the dash...or the Ox relay is failing. When it does some systems won't operate like the starter or fuel pump or ignition. I can't tell you which one is that relay but all...were..in the older models..located above the glove box on the upper frame. A wiring diagram would help ID the wire colors going to it. I have one for the 2014-2017s which I will post below. May still be the same.

Download it soon as these links expire. Good luck. It can also be a bad ignition switch or kill switch too. Flip the kill switch on and off a few times to work the contacts. They are not water proof and corroded contacts are common in these.

I figured it out. It was the starter relay switch. I wiggled it and it fired right up. Now I need to get it out and replace it.
