Mustang 342 skidsteer will not start

[MentoneMike]

Hoping to get some help. My Mustang 342 will not start. It has the Kubota D1402 3 cylinder. It is literally in the back 40, so access is not easy. Drove it there in January, changed all fluids and filters. Bled the lines, replaced the relay.Fuse is good. All I get when I turn it over is white puffs of fuel out the exhaust.
Have not replaced the glow plugs. Just don't get it why it will not fire.
Anyone have any suggestions?

Does it have auxilary hydraulic control like a bobcat skidsteer?
Perhaps it is activated.
I believe its one of the pedals.
Bob would crank over and almost start, but aux hydro was activated and lines were capped so pump was deadheading and stalling engine before it started.

If you're getting fuel smoke, you've got 1/3 of the equasion (need fuel, air and compression to run). So focus on air and compression...

could also be a glow plug issue.

Thanks Guys. I am not aware of an auxiliary hydraulic control like you say. The center pedal does lock the bucket from being used, but nothing else. It does seem like something simple, like a fuse blew, but its OK. I do hear the click when I hit the plug button, but I guess they could be bad. Weird though it ran fine until I started switching out fuel lines. I did get all the air out, I know that. I did accidentally hit the relay with wrench before I disconnected the battery, reason I put a new one on.
Wondered about a bad neutral switch or something.

Are you getting fuel to your injection pump? Does it have an elec lift pump before the injection pump

The center pedal is the aux,when activated it would prevent any hydraulics from working if lines arent connected to anything.

Need to test glow plugs if its cranking normal.

To shut it off do you normally pull a cable or turn the key off?
either way make sure the shut down lever on the side of the injection pump is all the way forward.
Set the throttle to full and re-bleed all the injectors lines right at the injectors, I'm betting air is still in the lines.

Turn the key off. Good thoughts, I'll try to bleed the lines again, did not push the throttle all the way and double check the shut down lever, never looked at that.
Last time I drove the skid loader was with that aux pedal locked. Would leaving it that way prevent it from starting? It is cranking normal. Good strong battery.

I have a NH with a Kubota engine and I have to have the throttle lever pushed all the way forward before it will start. If my aux hydraulics are engaged it will not start even if it is warm

Finally got to the thing last Sat. Pushed the throttle full forward and double checked the
aux hydraulic lock. Dang thing started! Thanks a ton. Did die several times but noticed I had not gotten one fitting completely tight and was releasing diesel fuel. After that I was good to go.
Thanks for all you guys help.
