Has anyone had bad ecm. I think I do because my fan runs all the time and it leans out and doesn't respond to O2 signal quickly. I replaced the O2 not the issue I have a afr gauge on it and it goes lean but the computer doesn't respond. I can drive part throttle and the engine dies and comes back back and forth fuel pressure and ignition are good. Anyone have a issue like this or have any input?

Trace all your wiring from O2 switch all the way back to the ECM. Look for rubs that could cause shorts in your 02 harness.

We had a similar problem with our T4 and the wire was rubbing on the starter and all of our wires had melted together in the 4 wire harness.

Also the dealer let us pull our ECM and he put it in a new trooper just to make sure it was not a ECM problem. Good Luck.

      Travel time question
      By Greg Kilgore
      I would really like to know what you guys think about this. I'll try not to ramble and make it as clear as I can.
       
      I took this new job with companyX as a fiber splicer a year ago. I have a 45' bucket truck and 10or12 x 8 ft enclosed splice trailer I have to take home. Within the last 6 months all the management in the splice dept left. Now the power/construction management and higher ups are filling in. Just recently we were told travel to our 1st job is not payable even though we are in a company vehicle. 
      We are union so I asked the union business manager about this. His reply was be grateful you were paid travel as long as you were and that you don't have to drive your POV to the job.
       
      Last week I had 50hr total. The job area is 4-4.5 hrs away. My time was reduced to 44.5 hrs since we were told this travel thing on Tuesday of that week. I wasn't hired for this area. I was hired for area a lot closer to home. 
       
      Pay is good. Work is not hard. Insurance is through the union and so far pretty good.
      But I hate the thought of having to work extra just to make a 40hr paycheck. Anyone who has to drive as part of their job knows windshield time is not easy.
       
      Anyway what do you guys think. Should I look for a different job or just suck it up because of the decent pay and health insurance.

      "R" light will not go out when the UVT is in any other gear. Is this an issue?
      By Steve B
      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      2011/14 Hisun 500 fuel issue
      By Hi sun 500
      hello everyone, i just joined this forum to try my luck, few days ago i bought an old (dont know exactly), 2011/14 hi sun 500cc ""carburated"",  was not running at the time, but i fell was a good deal and decided it to bring it home to play with it, this is the issue, i bought and installed a new carb, and pump, i repositioned the battery location and upgraded to a "car batt", reconnected the fuel lines and started it, but it only runs with the choke ON, i checked the bowl, it does have fuel,but for some reason wont inject it to run, i came across a video that say that ""the body small tank had to be connected for the cart to run" (was deleted when bought), sure enough i got it to run sporadically , but the so called ""small body tank'' often runs out of fuel and wont refill itself , i had to couple times do it manually, so how does that small tank works ?..what does it do?..and why if  bypass it , the cart wont start?....any help?..thanks so much!!!
