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

      Coleman UT400 - 6v or 12v battery?
      By Rainman
      I want to put a charger/maintainer for my Coleman UT400 for the winter and need to know if it uses a 6v or 12v battery.
      One search online showed a 6v, but another stated 12v..
      I can look at the battery, but after taking the seat out you cannot see the top of the battery without also removing the top plate under the seat and at 8 degrees outside, I'd rather not be out there too long.
      Can anyone verify what volt (6 or 12) the batter is?
      Thanks in advance ...

      2015 Massimo 550 Throttle Position Sensor issue
      By TexAcoon
      I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.   
      From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
      My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
      Thanks!

      Losing Fuel / Prime 500cc
      By Buddee
      2010 Hisun 500 - Carbed'.  She sat for about 3 weeks since last use.  Couldn't get it started.... has spark but plug was not wet.  Bought new plug, cleaned the carb, confirmed fuel pump (pulse type) is working.  Still nothing.  Put gas in the plug hole.... started right up and idled as normal and drove perfect.  Used it for the rest of the day without issue.  Tried to start again next morning.... same problem.  Poured gas in plug hole again.... started up and best kind again.
      Anyone have any insight to what's going on?

      2017 Massimo MSU 500 top end kit
      By Jerrys500
      Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
      Thanks Jerr
