2012 mule 4010 gas won't start

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.

I'll check that too

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

      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.

      My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
      Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

      Bought a Massimo 500 last night. Stopped and filled it up on the way home and I put the wrong gas in it. Is there a drain plug on the bottom of the tank that I can get to or will I have to siphon it out?

      I have a 2012 Massimo MSU 500 that died. I found that it didn't have spark and the fuel pump wouldn't run. Checked all fuses and none were blown.
      Went through and replaced the ignition coil, HT lead and spark plug. Still no spark.
      Thought it could be the fuse/relay box because I didnt' know much about the machine at that point so I replaced it. No spark.
      Then I replaced the ECM just because I was running out of ideas. No spark.
      I removed the 9 pin connector and hardwired it making sure that they were no wires got swapped. Still no spark.
      Then I replaced the wiring hardness. In doing so, I replaced the 9 pin connector with new ones. I made sure all wires were matched up between the engine harness side and the other harness assembly. Still no spark.
      I have no other ideas what to do. My fuel pump doesn't kick on and I have no spark. I have 12V on the fuel pump, ignition coil and fuel injector, but no ground from the ECM control.  I unplugged the fuel injector and waited for a diagnostic code but nothing ever came in. It makes me think that the ECM isn't powering up. I've checked for 12V on pins 18 (purple wire) and 15 (white and black wire). I also checked for ground on pin 2 (black wire). All are good.
      I am out of options here and I have no idea what else it could be. I have all connections redone and are coated with dielectric grease. I've checked all easy things like fuses and making sure I have 12V in the right placed. I would appreciate any help.
