Ok thanks for the thorough explanation. I really appreciate it. There is a ton about green energy that makes no sense!!

Thanks again everybody for the advice. I have ruled our cam and crank sensor, (by replacing like a dummy). I figured injectors weren’t opening and thought that could be the problem. Unless I bought bad sensors then that’s not it. Virgo can you explain to me again how to check pulse. Also I keep...

I have had this machine for 6 years and have been an operator for over 20. I’m very familiar with the operation and safety features, I’m just not a mechanic I do appreciate all your help, but I’m 100% certain it is not the switch. When I get into the diagnostic screen of the machine, it will...

Thanks for the help. I have used that switch several times. In the past to keep my young son from starting the machine. It has never cranked when switch was pulled

I’m not close to mine either but that’s the first thing I checked. I let my dad borrow it. He unloaded it off the trailer, greased it, trammed 30’ and it just shut off. My machine will not crank if the switch is not in the run position.

The switch is in operating position. If you engage the switch the engine won’t even crank.

No errors showing. I accessed the dealer service portion of computer and did a scan it comes back clear

Wow thanks for the advice I didn’t realize that. I have checked oil level and it is good. But I will check injectors for pulse. Thanks a million for the response

Thanks for the advise. I have tested the voltage to the injectors, when I crank the engine the injectors show voltage. Which makes me think it’s more to do with fuel rail pressure. I’m no mechanic for sure just a lot of late night research and brain storming!!

Thanks for the comments. I will order a WSM. I have access to one for an 80 and it seems to be the same setup. The machine is def a common rail. It does have a computer system. I figured out how to get into the system and do a scan. It shows no error codes. I know the system will show codes due...

Hi thanks for the response. Yes engine cranks but does not start. It does have a manual fuel shutoff on filter but that’s it. Fuel is controlled by a SCV (suction control valve). No seatbelt safety shutoff. I’ve checked all relays and fuses. No I do not have a WSM. I’ve checked and it’s getting...

I have a kx040-4 it was running fine then shutoff like you killed the switch. Emergency stop button has not been hit. Have fuel coming through the filters and up to the injectors. Any thoughts?

I have a kx040. I am receiving fuel to the injectors, but seems there is no pressure. Is it possible the overflow valve on the pressure pump could be stuck open? Is there a simple test that can tell me? Also if I unplug the SCV will it give full fuel to the pump, or no fuel? Any information...

Since the SCV will need programmed I believe it would be best just to wait and have the machine scanned to confirm that is the problem.

Thank you for the response. I have good fuel coming to the pump. Where is the diagmaster port located on my machine.

Hi all. I have a Kubota kx040-4 that just shut off while tramming, like you turned off the key switch. It will crank but not start. It has zero error codes, I have some fuel coming out of the injector pump but doesn’t seem like there is much pressure. Is there a check valve in the fuel rail or...
