Frozen Injector or?

[strum456]

Our 345d (201 3cyl) was running fine when parked in the garage a few days ago. We got it out to run the snowblower this morning and it's running on 2 cylinders. It has a block heater and started on the first crank. I suspect something is frozen in the fuel system. I don't see how there could be any moisture in the fuel, both the fuel tank and tractor are kept inside. There is never any water in the filters on any of our tractors What is likely to be the problem?

Drain the fuel filter to check for water. If none found add some Power Service conditioner and run it awhile and see if it helps.

Have you kept both tanks over 3/4 full?

A couple of 100w lightbulbs or a heat source pointed at the fuel system might help. Check to see which cylinder is cold and pull the injector. Swap to another cylinder and see if the miss follows.

Before pulling injector loosen fuel line at the injector to see if the pump is pushing fuel to the injector.

If something is frozen in the fuel system and only one cylinder is affected, it isn't the tank, lines, or filters, or I doubt it would run on 2 of the 3 cylinders, since those components are common to all three. It would seem related to the one lazy cylinder. See if that injector is getting fuel to it, as has been suggested. If it is it could be the injector, bad injector pump for that cylinder, or maybe a valve issue.

It turned out to be the fuel filters. I cracked each injector, but couldn't narrow the miss down to an individual cylinder. There was a small amount of water in the sediment filter, along with a lot of rust paste. I forgot that this tractor came with fuel system issues when we got it years ago. Tank removal would be no picnic, so I suppose I should change the filter s little more often. Thanks for all the replies.

Keeping your tractor and fuel storage inside will help keep moisture out only if you run a dehumidifier as I do. The moisture gets in through condensation not rain. Keeping the tanks close to full especially during times of the year when cold is abruptly followed by high humidity is the best you can do.
