well i have it narrowed down to my fuel pump and rad fan that are keeping me from enjoying my trooper, when i turn the ignition all the way over to where the fan and pump are suppose to kick in they do not, but sometime will. i ended up running a direct line to the fan and fuel pump and they are working but it still will not fire. i took off the fuel rail system to see if the injectors were giving fuel but they were not. so is it something to do with the computer? i replaced all the relays too just to make sure but still no go. is it because the computer isnt sending a single to the injectors to give fuel? im not a mech but i am getting frustrated cause no one around here knows anything about these things. and everything i know is off of this forum witch has helped me with so many problems that i have fixed. i am hoping to be helped again. is there a way to wire it to make the computer send a signal to the injectors to give fuel? if that is even how it works?

Check to see if your getting power to the computer. I would use a multi meter to check the wire going into the computer. Can't tell you which computer terminal it is but Kinarfi probably can. I found that with my original computer that I had to ground the computer aluminum case itself or it wouldn't work. I know, go figure. Make sure the ignition switch is forwarding the 12v power to the computer. Some on here have had bad ignition switches. Trace the 12v from the battery to the ignition and on to see it is getting where it needs to be. Good luck.

      MSU 500 Fuel Pump Ground
      By Kierobi
      Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it. 
      Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming. 
      Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light. 
      Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
      Thanks in advance and hope this all make sense!

      Altering running lights
      By MilSurpYinzer
      Anyone decent with electrical work that knows a good tutorial on how to make my running lights switch off all together but also turn back on when I need too? I'd assume that my lights are hard wired to the battery or the fuse panel.
      Vehicle is a Kawasaki Krx 1000
      I'm looking to ad IR driving lights for night vision and short of just putting black tape over the lights I feel this would be a more efficient option and it would be cooler.

      Utv wont start and broken fuel injection wire
      By Jeff freeman
      I have a Coleman 550.  Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness?  Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.

      Fuel injector replacement Massimo 500
      By Eman85
      Pulled fuel injector to see if I could clean it or if it's stuck open. Had a slide on clip that was really tough to get off. Don't see how the clip is supposed to lock into the plastic part that the injector slides into. Any videos or pics of injector replacement?
