Diesel won't start after it ran out of fuel
There will be 2 reasons. Either the very low level in the tank allowed the pump to pick up some of the sludge that generally accumulates. This would mean a strip down and clean. The other is that you have developed an air lock. This is easier to cure but potentially a bit dangerous to health!! Where the fuel lines feed the injectors, loosen the nuts off, just a bit, to allow any air out. Put new fuel in and try and start the car. DON'T stand near the engine bay as the pressure it comes out of those lines can inject fuel through the skin!! Crank engine until you see fuel escaping on in engine bay. Tighten them up and try and start car properly. If it starts then turn it off and allow discharged fuel to evaporate. After this if it starts but runs "lumpy" chances are still have an airlock in one of the feeds to injectors. DO NOT DO THIS WITH A WARM ENGINE. Be careful of the fuel, at all times

At the rear of the injection pump there are four lines, each goes to an injector. loosen the flare nut at just one injector. crank the engine over until you see fuel spitting out. Close the fuel line,vehicle should be running. If not then its something else check the fuel filter, fuel shut-off, and check for any fuel leaks.

check fuel rail pressure with a gage from renting from auto shop shold hold 30 PSI for 60 seconds if not replace fuel pump.

That's what happens to diesel car when they ran out of Diesel, they the pump sucks air in then you have to Purge the line until the air is out. Good luck

This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.
