We have just gone through and ice storm and days below freezing. My 2004 L 3400 will not start which is a first in 25 years of Ohio winters. I suspect my fuel control solenoid is stuck with ice. My question is where is it located so I can try to thaw it carefully with a heat gun? Thanks to all for any help.
L 3400 fuel shut off solenoid
- Thread starter tonypresti
- Start date
Here is the solenoid and where it is located.
If you suspect the solenoid, (which is an unlikely failure), remove it briefly. Remember then you cannot stop the engine with the key!
I think you will be more productive on checking out the fuel filter for water and ice.
When did you buy the diesel fuel you are currently using?
The only free WSM for an L3400 is from Scotland and may not represent the safety controls your tractor has concerning the stop solenoid.
From looking at other tractor models the same part fits, I believe the stop solenoid on your engine has two internal coils. a Pull in coil to actually move the plunger and a hold coil to keep it retracted once moved by the pull in coil.
Before removing the actual solenoid I suggest you check for power at the solenoid electrical terminal. Unplug the connector from the solenoid and check for power on the wiring harness connecor using a test light in both the ON and the START positions of the key switch.

As stated before. Your fuel solenoid is the least likely culprit. If you hear a "click" at the solenoid, chances are that it is working.
Gelled fuel is more likely.
Gelled fuel is more likely.
Thanks Dave but the solenoid does not click which is why I suspect it is the problem. I was thinking it may be stuck by being iced from the rain and ice storm we just had. I also saw the parts diagram online but still can't locate it. I will try again soon.

I think on that model the solenoid only engages for a short period of time when you shut the tractor off?
Ok, then I'll check for ice in the fuel bowl. Hope that does it. Thanks again Dave!

Well no ice, slush or water in the fuel bowl. I cleaned it and replaced the bowl. Clear clean fuel then filled the bowl. Pre-heated and cranked but still did not fire I'll put a multimeter on the solenoid to check for current then get back to you. Thanks Wolfman
