Hi everyone. New guy here. This is a project UTV. A 2015 Massimo MSU 500. Cranks over fine  BUT no spark, no fuel pump power and no injector cycle. Everything else has power and works ok.

with my fluke meter, I am getting 12v to the coil and to one of the red wires on the fuel pump plug.

The fuses in the relay box are all good. I wouldn’t think a CPS would effect the fuel pump, just the spark.  Could this be  a bad ECU? 
Thanks.

Can anyone tell me if their fuel pump and injector cycle when you turn the key to the RUN position.

My thinking is that if they cycle with the key on before cranking, this rules out the crank position sensor. 

Thanks

      2021 Axis 500 Head Bolt Torque specs
      By Greg Kilgore
      Got a 2021 Axis 500.
      I'm needing the head bolt torque specs.
      Manual states 38nm.
      But saw a video Hisun put out on YT for a 550 stating 50nm + 45° turn of wrench. Didn't think they would be that much difference on a 500 and a 550.
      Seen another YT video on a 2013 500. He did 38nm.
      Really only want to do this job once and done. And done correct.
      Anybody got the answer?
      Going to start this rebuild in a few once this weather brakes. Flooding and then snow and cold here now. But spring is around the corner and the wife has to have this fixed or a Honda pioneer may be parked in driveway soon. She has to be able to ride.

      As with any forum you join, there is a requirement for an obligatory introduction... and that seems fair. How else do you get that first post in there without jumping in with some stupid question right out of nowhere?

      Hi. I'm Space Ghost. Well, not really, but that was my call sign on my last deployment before an IED made me non-deployable, and I an now retired/disabled, and living on my wonderful VA disability. I did almost 28 years in total between the Army, Army Reserve, and National Guard. 1 deployment with the Reserve (Desert Storm) and 3 with the Guard (1 pre, and 2 post 9/11)

      Married (going on 30 years) one of each. (both out of the nest)
       
      Just picked up my first side by side a couple days ago. A 2020 Can-Am Defender HD10 DPS 6x6. 

       
      It's in pretty good shape, but as you can probably tell, it's sitting a bit high. Former owner put a lifting collar on the shocks. 

       
      The good = almost 17" of ground clearance. (30" tires) 
      The bad = incredibly steep driveline angles, and a pretty stiff ride. 
       
      They will be coming off. 
       
      Other than that... clean as a pin and appears very well maintained. 
       
      Looking forward to seeing what this forum can bring, and hoping I can bring something in return.

      Is there a better performing higher volume injector than what they come with or what is the best replacement for the original?
