First, check the fuel shut off at the tank.
Second, check that the shut off pull is connected correctly.
It could be that it is holding the lever to shut off instead of run when pushed in (yours may be different than mine.)
Service manual for Long 360-460-510 series in pdf.
Not too sure but this is available here (link)

May be helpful if you do not have it.
Next, l would be inclined to check the lift pump and filters. It could be that the lift pump is not getting fuel to the injector pump. There is a 13 mm bolt on top of the fuel filter, crack it or remove it (I had to remove it on my 2510).
Crank the tractor (I used a remote starter button so I could watch the filter) until clear diesel comes out. Close the bolt.
Once you have the lift pump and filters working, bleed the injector lines.
Do this by cracking the lines at the injector (all of them), turn over the motor until you get clear fuel with no bubbles. Then tighten up the fuel line nuts.

Be careful about how long you crank the engine. Give enough time to cool off between crankings, and do not crank longer than 15 seconds.

Please let us know how it goes!
