Kubota RTV500 fuel issue

[Jowald]

Hi, I have a rtv500 with a fuel issue. I get gas to the injector and have over 30 PSI fuel pressure. I have replaced the injector hoping that would fix the issue but to no avail. Anyone got any idea what it could be. Would appreciate to help cause I'm completely stumped.

I assume that you checked the spark?

 

[Jowald]

No I haven't I also forgot to mention the injector is getting fuel but isn't working so the spark isn't the issue, because the fuel isn't getting past the injector

Does this engine have an injector driver?

It's electronically fuel injected.... just to be clear... I'm still pretty new to this

 

[aurthuritis]

I would suspect the low oil sensor? And i would first check the injector driver or the relay that controls the fuel injection.try swapping relays

 

[Jowald]

ok thanks. should the power to the injector pulse or not?

 

[aurthuritis]

The injector has to be triggered to inject at the right time.There has to be a signal sent usually from a reluctor on either the crankshaft or the camshaft. These would be either the cam position sensor or the crank position sensor. If the sensor is dirty broken or out of adjustment the signal to initiate injection is missing. There should be some sort of ecm or engine control module. It probably isn't being turned on by a faulty relay?

Ill have a look at those relays.

Always start with the simple. Check fuses? Relays? Check clean grease connectors? Make sure the ecm is properly grounded.get on messicks and look up the schematics and parts descriptions for your model. These pictures can be handy for identifying the senders and ecm etc.

checked the ecm and and relays...injector is getting power and everything. The injector has around 40 ohms of resistance... not sure if that's an issue... factory spec is around 14. Haven't checked out the sensors yet.
