2012 mule 4010 gas won't start

Recommended Posts

I just got this thing a few weeks ago. When I got it it would run but try to stall out if I got more than an idle. I replaced the fuel pump tonight because my jeep had the same symptoms when the pump went out on it. After I replaced the pump it will fire off but die instantly. Any help?

Check the gas cap gasket. My 610 mule ran like shit after an hour of running. The gasket in the gas cap was blocking my vent hole in the cap. The gasket was also upside down according to the parts diagram. I havent had an issue yet.

Possibly as fuel pressure regulator? What about the filter?

What would the fuel pressure regulator be and how would I check it?

I'll check that too

The regulator is likely in the tank. Did you replace the whole assembly, or just the pump?

Just the pump

Personally I'd likely put a lot of effort into making sure the injectors aren't gummed up from the gas that's sold these days. I understand the gas that's available, causes most of the problems like yours.

After posting earlier, I did a quick Google search, and it seems that these gas units are a bit finicky about gas quality, and the ethanol is the worst. So I'm thinking I'll revise my opinion towards the regulator.

Since you recently acquired this mule, you probably don't know much about the mechanical history of this thing. So I'd start with the basics. I'm certain it's in the fuel system, although I've been wrong many times before. And barring any unforseen issues such as your pressing the throttle, prior to starting, (some people do as a habit of starting). My gut feeling is the injectors. Although it could easily be one of the sensors, but I'm thinking that you'd get a warning light if that were the case.

Started messing with this again today. Pulled the fuel rail off and couldn't get any gas to flow through the injectors. I'm going to run down to the hardware store and get some carb cleaner and try yo clean the injectors. Is there any tips on cleaning them

You tube has some good video on this, where they use a battery and carb cleaner. I've never tried it, but I can't see how it could fail to work.

      We have been having all kinds of fuel issues with this ranger.  When you try to start it when it is cold outside, it does not want to start.  It will crank over fine but doesn't start but if you stop and come back 10 minutes later or so, it will start up.  But even then, it is idling real bad.  Usually will die a few times before you can get going, really have to feather the gas pedal to keep it alive.  Once it gets warmed up, it does start better but something still not right.  Even when it is warm outside, it will start up but just doesn't idle right.
      I bought a fuel pump kit, not the whole assembly, just the pump and replaced that and the same thing happens.  I am in the process of trying to check the fuel pressure on it but the fuel pressure gauge I got from our local auto parts store seems to be defective.  Had it hooked up and can't get the gauge to show any pressure at all yet it will still start up.   If it does have the correct pressure, what would be the next place to start looking at?  If it doesn't have correct pressure, is there something else on the assembly that would cause low pressure?  We checked the voltage on the connecter and one gets 12 volts for just a few seconds and the other one gets 4.9 volts.  The other 2 show nothing.  I am guessing the one with 4.9 volts is for the fuel gauge sender and the one that has 12 volts is the pump.   When you take the fuel line off on the engine side and turn the key on, how far should it throw fuel out?  
      We have taken it to 2 shops and neither one was able to do anything with it, one said there was nothing wrong.  Not sure if they really did any checking or what or they just don't know what to do with it.  
      Would the whole fuel pump assembly out of a ranger 570 work with the ranger 800?  Would I be able to swap them without any issues?  To buy a whole new assembly, it's around $400, don't really want to spend that much not knowing if it will fix it or not.

      Dipstick shows pale color, dont think its water, smells like fuel, oil changed one week ago, level is very high.
      First I thought it was water condensed into the oil...but someone pointed out the smell, and it doesn't look white-milky. And a half qt or so in one week?
      So is it possible to get fuel leaking into the oil?

      Hi, 
      Just purchased a 2015 Massimo 400 EFI. While I was cleaning the air filter sponge I noticed fuel was dripping out of the air box. Any ideas where this may be coming from? 
      Since it has electronic fuel injection I wouldn't think a carb float would be stuck or something like that. 
      Any advice is appreciated.

      Hey folks. I recently acquired a pre-owned Hisun 500, carburated. And surprise... it has issues.
      When cold, it typically starts without any issues, but once it warms up it tends to sputter and stall out. When accelerating, you can also feel it hesitating occasionally, and when you stop or put her into reverse, she will often stall.  The fuel is clean, I installed a new fuel filter, and the air filter is clean. Though the fuel pump appears to be working ok, it makes a strange knocking sound whenever power is put to it.  I've never heard anything like it, and I'm not sure if its shot or just a cheap Chinese pump thing. I have an aftermarket pump coming, and I've ordered a new ignition coil as well on the off chance that it is faulty. I am hoping replacing these two parts will solve the issue,  and if it does I will post the results here. 
      If not, anyone have any other ideas?  Also, I've noticed it is very difficult to find parts for this make... any suggestions on a good source for Hisun parts? I appreciate any comments or insights.
