Hi...

I am having an issue with the fuel pump fuse blowing as soon as I turn the key on. The utv was running great and all of a sudden it blew the fuse and now wont run. The unit only has 250 miles on it. Any ideas on where to start? Im in western north carolina and cant find anyone to work on it. Thanks.

Sounds like a dead short to me. With 250 miles, I really don't think it could be much. I'd look underneath the thing, at the wiring. A lot of times sticks, or logs and stuff gets kicked up and can damage the wiring. Other than that, it could be the pump itself. Try un plugging the wire to the fuel pump, then turn it on, see if it still blows a fuse. If not, use a test light to see if you've got 12 volts at that plug. If there's 12v at the plug, then the pump is the problem.

Thank you kenfain for your insight! Sounds logical. I will give that a shot in the next day or two. Do you own a Joyner and if so where have you found the place to get parts?

I've got a mule, it's not for play. It's for work around the farm. But all off road vehicles can be subjected to a lot of abuse from underneath. I installed a large plate of 5/8 thick bed liner type plastic under the vulnerable areas on the mule. But I'm always pulling jammed sticks out from various places on the thing. And the mule seldom sees speeds over ten MPH. So that's the first thing that comes to mind with a relatively new off-road vehicle.

I'm not sure if I know what a Joyner is. I've seen the pictures posted by other members. They look like fun, kinda like a mini sand rail. If parts aren't available locally, looks like online is going to be the way to go. However, as popular as these things seem to be, there's got to be a dealer someplace within driving distance. I find the internet has way more choices for after market parts. As far as OEM parts, I like the web for those also, even car parts.

You mentioned not having someone local to service the unit. I'm very cautious about letting people work on my stuff. I've been burned too many times. Buy a service manual if you can, it's the best way to go.

Thanks Kenfain.....

Well, I had my neighbor take a look at the machine for me (I am out of state so I had him look). He said he disconnected the wiring from the fuel pump and turned the key and the fuse still blew. So, I am guessing the pump is ok, just as you suspected. Then he said he took out the relay and turned the key and again the fuse blew. So, are we right in assuming there is a dead short somewhere between the fuse and relay? Electical issues are such a pain.

Thanks for any insight.

At this point, a wiring diagram could be helpful. But at the least, you should see about finding what the wire color, and the routing of the fuel pump hot wire. On a small machine that doesn't have a lot of electrical circuits, you could probably just look and see where it goes.

Doing the easy stuff first, carefully inspect the wiring bundle you've identified as belonging to the fuel pump circuit. I usually start by careful inspection of the exposed underside. Sticks and logs get kicked up on the trail, sometimes damaging the wires. Often the culprit is still hanging there, so be vigilant, it could save some time. If this quick inspection doesn't turn up obvious cuts or contusions, you'll have to inspect the whole bundle from key to pump. Check wires for physical damage. Check plugs, switches, relay, and don't forget the ignition switch itself.

If that doesn't locate the problem it's time to use an electrical tester of some type. I'll use both a test light, and a meter, set to the ohms scale. That's for testing continuity.

Your problem does sound like a dead short caused by a break in the insulation. These are typically fairly easy to spot. Sometimes all you can see is an un natural bend in the wiring bundle. Closer inspection reveals the break. In most cases it'll take less time to find the problem, than it took me to type it. Keep us posted on any progress!

      Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load.  Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out.  It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature.  I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter.  No check engine light.  I don't have a code reader for this.  Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking.  I've changed the oil since then twice to clear and clean everything out, and it seems to be good.  Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77.  What should I try or consider next?

      Hi, 
      New to the forum. 
      Came here looking for some experienced UTV users who can enlighten me about which brand should I pick for my very first UTV or SXS. 
      I'm between 3 brands and 3 models: 
      *Kawasaki MULE PRO-FXR   1000.
      *Yamaha wolverine rmax2. 
      *Can am Commander XTP. 
      The use I'm willing to give it is mostly to go to the range with my wife, load steel targets and all our shooting gear, we shoot a lot, rifles, Shotguns and Handguns for practice, training and competition. (Range is about 10 miles from home) 
      But also I want something that I can take to the trails and have fun on dirt, mud, rocks, puddles or creeks. 
      Any objective information will be appreciated, specially which is more reliable and durable. 
      Thank you and happy 4th of July.

      I charged the battery reconnected everything but utv will not start and nothing comes on when key is turned. such as headlights, dash lights nothing.

      I purchased a 2008 American Sportsworks Subaru TW265 UTV, with no manual and no previous knowledge. When idling, the steer column shakes uncontrollably, is very noisy, and might be from vibrations from the engine. Logically, I am thinking engine vibration moving up the steering column. I found a schematic, but that has not helped in identifying the specific problem.
      Any thoughts? Suggestions?
      Thanks so much

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.
