Hello All,
We have exhausted all possible troubleshooting steps, now we are in need of some help.
Vehicle cranks but will not turn over. Things we have either replaced or tested and are now known good:
1. Fuel pump (new)
2. Fuel sensor (new)
3. Fuel injector (new)
4. Battery (new)
5. Spark plug (new), spark tested
6. fuses (12v to all)
7. we have 12v at the injector module and 11 ohms resistance
8. we have fuel in the fuel line to the injector
9. we have fuel at the spark plug
10. we have injector pulse, verified with noid tester
11. brake safety switch tested (couldn't find a separate switch assuming it is using the brake light switch)
12. seat belt buckled and seat in place (again, not sure if this model has these features)
13. replaced air filter
14. replaced several air hoses
15. flushed radiator and replaced with diluted antifreeze
16. Drained and cleaned the fuel tank prior to replacing the fuel pump.
Any ideas, we are open to....Help!!

I recently purchased a new Kubota RTV520. When i try to start it i have to do the cold start procedure every time. Once it is running for a few minutes i can restart it without any issues.
The cold start procedure is turn the key to start position and let the fuel injection system turn on and stop. Crank for 10 seconds and if the unit doesn’t start, turn off and repeat the process 30 seconds later.
If it hasn’t been used for a week and i try to start it i have to repeat the cold start procedure at least 3 times until i get a successful start.
The dealer says this is normal and its not a malfunction on the engine. I feel like its weird for a new machine to have this starting routine.
I live in south Texas so the weather is not extremely cold.
Is ANYBODY having this problem? I am contemplating returning the UTV but i want to know if this is a common problem with the new 520 model.

Hi All,
Just picked up a 2020 UT400 that my 80 year old father will be driving around the farm. We purchased the machine with a few "issues" and they lowered the price accordingly. Small stuff like passenger size mirror and back reflector was torn off by a Tractor supply employee, which we will order replacements for. Also after further inspection, whoever assembled it did not put a few bolts in the rollcage and aren't in the glovebox, so will be having to order those also.
Anyway, there are two initial things on the UT400 I'm not sure what they are or for. The first, there is a square white electrical connector with about 8 pins hanging form under the middle of the back bed - I don't see another one to match up or plug into it, so wondering if this is pre installed optional connection for like towing around a sprayer? Anyone know what this is? Also, there is a 10 inch black rubber hose that is zip tied to the back A frame on the passenger side. I watched the assembly video and it doesn't mention one, so don't know what this hose is for - anyone know?
Also, has anyone come up with a "fix" or work around for having to have the seatbelts plugged in or even in place? We aren't planning on using them and are figuring just plugging them in and wedging them behind the seats - didn't know if there is a way to just disconnect the "over 10mph gas starving" safety sensor.
Looking forward to seeing how this machine does for my father. I'm thinking about installing a suicide knob on it for easier turning for him, as it's a little stiff (compared to our Kawasaki Mule). Maybe with use it will loosen up some?
Thanks!

I am looking to buy a small UTV to do work around my property and priced a brand new Massimo T-Boss 560 through Lowes @ $10,500 out the door or a Dealer provided CFMOTO Uforce 600 at $11,500 out the door. Are there any glaring reasons to go with the Uforce 600 at an extra $1000? Is one model more reliable than the other? Any input greatly appreciated.
Thank you,
Jerry
