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!!

Hi
I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

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.

I have a Bobcat 2200 Diesel (built by Club Car) with a 2-weight Team Primary Clutch I want to rebuild, possibly replace. The clutch has an annoying rattling sound at idle and appears the rollers and weights are worn and loose. When I opened it up, everything looks clean and in great shape. It's just that all the moving rollers and weights seem to have way too much play in them, possibly causing the noise. I've searched for clearance and torque specifications with no luck at all. The UTV has less than 500 hours on it. Any ideas?

I have purchased a used Supermach700 (2008), It runs great after a new choke cable but. The temp sensor on the thermostat house is unhooked and can not find where it plugs back in. The fan has been un hooked from the sensor in the rad and cant figure out how it goes back together properly. The fan was wired to a by pass switch and i just always leave it on but would like to work it properly. I assume the sensor went bad and not changed.
any help would be great.
thanks
