Ls170 new holland skid loader fuel problem

jacksonduper · Jan 6, 2014

The last week or so I have been having issues with my skid loader. we are in southeast Wisconsin so it has been cold but I even had the issue on Saturday with temps in mid thirties. It starts and dies a few times then runs ok for about 30 minutes before it starts to sputter then dies. I have changed the inline filter and the spin on filter and still have problems. Fuel does not seem like it it gelled up. Could it be a fuel pump. Help please guys and I need to move some snow to feed some hay bales.

I bet the fuel is gelled. I would add some gasoline to see if it fixes the problem. If the fuel pump is on the engine you could check the fuel flow. You may have water in the fuel tank and its frozen over the fuel outlet restricting the fuel discharge. Hal

Throw that inline filter away untill warmer weather.My New Holland dealer told me to remove it untill after this cold spell.The metal inline filter from NH is better than the plastic one.They work on piles of skid loaders as they are the biggest NH dealer in WI.

DO NOT throw the plastic inline filter away. It's your first, easiest line of defence against water and if it is blocked you will visually see it. It's also a bloody lot cheaper than that spin on filter inside the back door. The first thing I'd do is make sure that the breather isn't restricted in the fuel cap. I find that when the filters are plugging up you notice the problem first at higher rpm's or heavier loads... it'll get the staggers or seem weak. If yours is simply cutting out then I'd wonder about the fuel solenoid. They do sometimes go bad... also make sure it has a steady power supply to the solenoid. If there's a problem in the lockout circuits or other things related to the ECM it will cut the power off of the fuel solenoid...
If it is gelling up, then some #1 diesel should cure the problem.
Also... if you have water in the tank... the siphon tube in the tank could be frozen. It happens...

Could be the fuel pump. I assume this model has primary pump before the injector pump?

Next time it does it, pull the hose off the injector pump inlet and see what kind of flow you get from the primary pump.

If it's a mechanical pump, you should get a strong, air free shot with every other revolution of the engine.

If it's electric, with the ignition on, you should get a continuous, air free, full hose stream.

If you get air, intermittent air and fuel, check for rotten, split, loose hose connections, loose pick up tube in tank. Air is easier to pump than fuel. This could also be a bad pump.

If you get nothing, could be gelled fuel, bad pump, clogged strainer in tank.

Pull the hose on the pump inlet, see if you get suction. No suction, bad pump.

On a few models the cap didn't. Vent properly and sucked the tank bottom into the pickup tube. Try running it with the cap loose or off.
