Stalling B2601

[Flower Farmer]

Great forum!

I have a B2601 with 134 hours on it that is slow to start and stalls after about 15 seconds running. I changed the fuel filter to no avail then drained the fuel tank and replaced the fuel still to no avail. Ran a bit of diesel deep clean through, still no change from what I can tell.

It’s about four years old, used mostly for tilling and mowing.

Any thoughts?

Does it ,by chance, have a second fuel filter that you haven't found? Another easy thing to try is to open your fuel cap to see if it's vent is clogged. that's a long shot because it takes longer that 15 seconds as a rule. Another possibility is gasoline in the fuel.

Nah

Thanks for the thoughts! Just the one fuel filter, and no vacuum problem with the cap (tried that first and subsequently, repeated loosening it). There’s definitely not gasoline in the fuel, drained it completely and filled it from a new jug of new diesel myself.

Runs for 15 seconds and quits?

Does it shut off like turning the key off, or does it stumble and slowly quit?

If the former, bet it's a safety switch. If the latter, could be fuel related.

If the former, bet is seat switch.

'slow to start' could be weak/bad battery especially if it's 4 years old. Not a lot of hours on it.

Stumbles and quits.

Does feel like a fuel issue to me, was hoping to narrow it down more than that. I’ve drained all the lines between the tank and the fuel pump and drained and replaced the fuel. I suppose the next step is to get a diesel mechanic here…

Battery seems fine - it gets started, just won’t keep running for more than fifteen or twenty seconds.

If it's stalling due to lack of fuel, and both the fuel filter and the fuel line is clear I would think the next thing to check would be the fuel pump.

But I'm not a diesel mechanic.

Try swapping in a different shutoff solenoid.

Pull off the line going into the fuel filter assembly. Pull the filter off and clean the passages in the filter assembly itself. They have been known to plug up with crap causing low fuel flow.

Any updates on your tractor?

Thanks for asking! Still not running. I cleaned out all the lines (didn’t help) and ordered a fuel shut off solenoid that will get here today, but I’m not holding my breath. The fuse on it was fine and it clicks audibly when I turn the key or remove/replace the fuse when the key is on, seems like it’s doing something!

Thanks for this advice! Didn’t do the trick, but I’m still trying! Getting a diesel mechanic out here where I am isn’t easy, just not many farms!

Well, swapping the solenoid didn’t do it, although after I tried that I popped the fuel pump off just to look at it, and when I put the whole thing back together it ran for like 25 seconds before stalling. Not sure what that means.

Obstruction in fuel line supply to pump?

 

[RCW]

Have you properly bled the fuel system of air prior to starting? I'm not sure what the procedure is on a B2601....

Is the fuel filter housing full of fuel when it quits?

Sometimes there's a restriction between tank and filter (often the inlet fitting of the filter housing as someone already mentioned) it will starve the filter....

With a hearty thanks for all the advice, I used an air compressor to blow out all the fuel hoses starting from the injector backward, and it did the trick. I made a mess of diesel everywhere, but I just mowed for half an hour, so…

Again, thank you.

Thanks for the update! Often new folks disappear after asking questions and we don't know the resolution.

So it sounds like there was an obstruction somewhere. Do you have an idea where in the system it was?

If it was the tank outlet, it's possible that could pose an issue again.

Was the fuel filter dark/black when you changed it? Do you treat your fuel with a biocide?

If it was an algal/bacterial obstruction, a biocide treatment of the fuel could help prevent recurrence. If it was trash like wasps, leaf pieces, etc. only removal will fix it.

Just something to pay attention to going forward.

Glad you got it running!

I’m nearly certain it was in the tank itself. I didn’t really know about biocide, but I’ll do that now.

Again, thank you all! I’ll be hanging out here for sure.
