Diesel injectors and bleeding

Pulled a stupid stunt and ran my 3600 diesel out of fuel yesterday and had a little bit of a problem getting it started again. I wasn't bleeding the injectors long enough to get all the air out which made me think.

Lets say you have a 3 cylinder diesel, you get two of the injectors bleed well enough to get it to fire but leave a little air in the 3rd. Will it go ahead and run OK or should the 3rd line (or maybe all 3) be cracked (one at a time) while it running to make sure you have the air out of all 3. I usually quit when it starts running and wondering if I need to take the additional step.
 
I generally crack all 3 injector lines at
the same time then crank it. Watch for fuel
then retighten the nuts. If it starts on 2
or even one cylinder that's ok. The other
injectors will bleed and "catch up".
 
I have done that (run it dry) on occasion on my Ford 3 cyl. I crack all 3 injectors at the same time. The trick is to crank it at full throttle to get the air out quick.
When you see the fuel start to flow tighten them up and you're good to go.
 
If its straight gears hook another tractor to it and pull it,a lot easier on the starter that way,about the only way to get Fiats to start sometimes.And another good idea is to keep the fuel tank full.
 
When I have had the problem in the past, I went back and rechecked each to ensure that I can tell the engine responded to the loss of a cylinder.
 
I open all that I can get to. Leave open until the fuel comes out. Then close them. The ones you don't bleed will clear themselves.
