Renegade 800 R4 high idle

Recommended Posts

I have a renegade 800 with fuel injection.  Someone siphoned all the gas out of the tank and left the cap off.  The machine was sitting outside and I really don’t know how long the fuel cap was off but I drained the tank and put new fuel.  Afterwards when I start the engine, the idle speed is at 2500 and will not come down.  Have since drained the tank , replaced fuel filter and added fuel injector cleaner.  Nothing has changed.  Hopefully one of you can shed some light on this problem for me.  Thanks in advance

Most or all fuel injected engines have a idle air control valve, it's usually electrical, not mechanical.

could be a problem with it.

      I’m working on a 98 mule kaf620. The fuel pump failed. It was making a loud clicking noise and would not accelerate. I replaced it with the cheapest pump I could find on amazon. It failed after a few days. We bought another pump from fuel pump factory and installed it. It began leaking from the seam in the body after about 10 minutes. I contacted them and they sent another new pump. After installing it, same thing; leaking at the seam of the pump. I’m not sure how to move forward. Does this pump have some sort of internal bypass? Being an electric pump, it cannot run all of the time. What am I missing? 
      Any help would really be appreciated, as a grandmother uses this to feed her cattle and is using a red wagon until it is fixed.

      Bought this machine a couple years ago and the gages didn’t work.  I have troubleshot this thing numerous times to no avail. Thought it may be a common ground so I individually grounded  the gages, didn’t work.  I have tested the sending units.  All have some resistance that changes as the engine revs or gets warmer.  Please help me.  Thanks in advance

      I am considering purchasing this (used) with 2000 miles on odo.  I have searched this site for information regarding differential issues.  My question is: What model years would have "up-graded" differentials?  I realize I will need to visually inspect both differentials once I get it, but just looking for a baseline as to if this particular year is more problematic, etc.

      I have a Q-Link (Rhino clone) and the fuel injector won't open up and spray. The fuel pump is brand-new and kicks on and primes to the injector but nothing comes out.
      I've cleaned and dielectric greased the electrical plug and the ECU plugs but no change. not sure where to go from here. Any help?
