I have a Massimo 400 Buck that won't start. When I turn the key, I get nothing, no lights, the meter doesn't light up, etc... I replaced the ECU and everything lit up, it cranked perfect, ran for a couple of minutes and shut down again. I have tried calling Massimo, they are pathetic, have been waiting a week for a return call. Any idea where to look?

No, it is not the battery, I have got it running but not sure why. I think there must be a contact sticking. I hit the voltage regulator with the handle of a screwdriver, everything powered up. the engine fired up and ran for a while then it shut down, had to hit the regulator again and it ran fine for the rest of the afternoon. This morning, everything fired up fine, I started backing it out and it quit running, had to hit it again and now is running fine. This is a new regulator, had the same situation with the old regulator.

      Help! Hub safety-hour meter switch problem
      By Texjpr
      2002 ranger 500 4x4 stopped running and wouldn't restart. Service manual wiring diagram helped identify the hub safety switch as the culprit. Using jumper wires to bypass  switch allowed the engine to start and run normally. Inspection of switch showed melted epoxy and a strong smell of burnt electrical. Unable to find replacement part either used or new. Is there a work around other than jumper wiring?

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.

      Lower Radiator Hose ID - UTV 400
      By PossumTruck
      Greetings,
      I have a client that wants me to install a heater of some sort to aid in cold weather starting (she uses it at her business, has had issues starting the last few days in sub-zero). I would prefer a coolant heater to a pan heater (silicone pad), but I cant for the life of me find the diameter of the coolant hoses. Heck, I'm not even sure if it would work as well in this application given how long the hose is compared to tractors and trucks I have installed them in. 
      Any advice you could give me would be GREATLY appreciated.

      24 Massimo Buck 250 Parking Brake Issue
      By felo72
      Hello all. I purchased a brand new Massimo Buck 250 EFI in June for our farm and I've had the parking brake fail on me twice. I have approximately 250 miles on the vehicle. The first time was less than a month after receiving the UTV. We all of a sudden lost brake pressure and it would not start. I tracked the issue back to the parking brake. Upon removing the chain cover, I noticed the brake pad was missing and the caliper piston was touching the rotor. I found a set of brake pads online and replaced them myself. It's worked for several months and just happened again. Seems like a design flaw. I'm reaching out to see if there's an upgrade option available, or if I should replace the entire caliper with the brake pads? Thanks in advance for any advise.
      I submitted a warranty claim, so I'll keep this updated with what Massimo replies.
      When I replaced the brake pads the first time, back in July, my Son made a video on YouTube to show the unique caliper design. Here's a link if you wanted to check it out:
