Mustang 940 No start - help needed

[badwagon]

Skid Steer help - Yanmar 4cyl Diesel cliff notes.. Went on vacation and had someone to try and move my snow on the acreage. He said it started, ran for about 30sec and then it idled down and stalled. - It WAS low on fuel, so I thought it was out. Fuelling and bleeding the system has got me back to the square 1 however and no change/improvement. - Is this acceptable spray from the injector? or weak? - Do I keep attempting to bleed the system by cracking the injectors one at a time?

That looks like a lot of fuel to me. The smoke looks like an onjector isn't spraying properly.
How does it stall? is it every 30 seconds? wonder if it's being shut down by a computer/timer (if fitted)

It wont start any longer... there is no ecu on this skid steer, bare bones Attempting to start it regardless of throttle position with exhibit the same symptom

After listening to it with the speakers on, i don't like the noise it's making while cranking. It doesn't sound as constant as i feel it should be. I'm not sure if it's firing a little bit causing the sound or not.
The smoke is a good sign, it may be a stuck injector.
I'd like to think that cracking the injector lines wasn't really needed, they should self bleed, but i know some pumps are different and may need purging.
One thing you could try is to crack the lines on all the injectors, crank it, listen and look at the smoke. Close them one at a time and look and listen to see if they make any change. Any that don't make any difference, aren't working correctly.
Hopefully this is of a little help

thx for the ideas I have cracked all injectors individually and none of them act any differently - replacing fuel filter tonight - going to rebleed the system and go from there

If it still doesn't come to life, do a compression test, still don't like the sound that you can hear in the video, doesn't sound constant like i think it should. Almost like compression is down or non-existant in a pot or two.
The smoke means you have some good compression. Generally white means there is fuel, just not enough heat for ignition. Black means ignition but not enough air for the fuel or bad spray pattern making the fuel not burn completely.
