It may be worth the one minute's time it takes to disconnect the solenoid , take it out and see if the engine starts. If it does push your finger into the now open casing to stop the engine. Also , in my Kioti ,there are two fuses that will disable the solenoid if either fuse is blown .
We checked the 10 amp fuse in fuse box and it was ok. don't know where the other one would be. We found two 60 amp fuses one on each side of tractor taped to wiring harness and they both were ok also. Read a post in 2011 about a 25 amp fuse for the stop selenoid but i dont know where that one is. If anyone knows that would be great I would check.
As far as disconnecting and taking it out, mine has a plastic guide that the pump removal instructions says to be careful not to drop when removing selenoid. If you can help me with that I think it would be worth a try.
Also in that same 2011 post( this person had wiring to selenoid shorting out and kept blowing fuses) someone replied about if you hear two clicking noises when trying to start you may have a bad relay of stop selenoid. So listened again tonight and here it is.
When key goes from off to on I hear and feel one small click in the middle 4 prong relay switch on fire wall.
When key then goes from on to heat I hear and feel a loud click on metal end of stop selenoid.
When listen for about 5 or 10 seconds after this I hear and feel another click in the middle 4 prong relay switch on fire wall.
Then when turn key back to off hear and feel another click in metal end of stop selenoid.
We never went from heat to start we were just checking for clicks in firewall relays and the stop selenoid.
It would really be nice if it were that second 25 amp fuse that i cant find. That would be much better than a possible injector pump failure.
thanks so much all help is appreciated and needed.
