Oil & Fuel Runs and then Quits or Won't Restart Unless I...

[Scooter74]

When blowing your fuellines .... do not blow the dirt back in your tank ......disconnect both ends !

Yes that's my thought. I will probably try draining the tanks into my diesel can and then look for any debris. Hate to try to remove the tanks but I want to see if it's sediment blocking the lines or a failing pump. The time it runs is almost consistent, around 30 mins before it stops so that, to me at least, suggests a failing pump. Debris or sediment should a random thing, whenever it happens to drift over and get sucked into the line but then I would expect the line to stay blocked. The tractor isn't moving, it's just sitting running the PTO at about 2500 rpm so there's nothing to dislodge it once something would get sucked into the lines

And also yes, it stops on it's own. I also got it running again we finished our chipping and shredding and then at that time I shut down the unit. Then it failed to restart, again making me wonder about the pump or injector pump perhaps leaking air into the system. So It quits after running a period of time, around 30 mins and if you stop it, it fails to restart without re-bleeding the system.

Rev up fast and then slowdown fast ......dos it die ? Then there s water in your fuel and inj pump . Time for the specialists !

Take the fuel line off from the tank to the filter when it quits....make SURE you have free flowing fuel.

I had an obstruction in the tank of my brand new Yanmar that was floating around in the tank, and would eventually float over the tank outlet, blocking fuel flow. The dealer started at the engine and replaced stuff BACKWARDS until they found it was that simple problem.

The obstruction was some plastic drill shavings (spirals) from drilling out the plastic tank to install the outlet fitting. (Found it when the finally removed the tank and rinsed it out thru a shop rag) They balled up together with a bug or two, and blocked fuel flow enough to kill the engine while running along. Then it would float away from the outlet fitting, fuel would flow again, and it would run fine until the next time it floated over the outlet.

HI,
I have a 2910i mind was doing about the same thing fuel pump went out replace with low pressure air tech from auto zone had low power then had fuel to everthing and not the injector pump my fuel stop had a blow fuse 5 amp replaced that all works fine now hope this helps.
