If you ran it out of fuel you prolly still got air in the lines. It my take a few times of bleeding and cranking to get her running again. If you have an air compressor you can open the bleed screw and then use the air hose and blow air in the fuel tank to help push the fuel back to the filter. You will need to use a rag to help make an air seal around the air nozzle and the fuel tank filler neck.

you have to remember that there is air in the lines from the CP3 to the injectors so it will take a few times. after you get your batts. charged you can have someone crank the truck for you wile you pump the primmer.

Could be lots. try and have someone prime while you crank it over. Leave the bleeder screw closed while you do it and do not crank it more than 15sec at a time then let it sit for a few to let the starter cool down

If ya loaded it up or vapor locked it most of the time it wont turn over. Be careful useing starting fluid. If the glow plugs are hot you could blow it up. Prolly what happened is it used what fuel it had in the lines the went to pulling air again. Its common for a diesel to get high revs when they start sucking air.

Got me.. I was told to never ever spray ether in our trucks. Someone else might have the answer.

i used to spray it in semi's to get them started you just have to use it wisely. or BOOM.... i think everyone has covered the ways to start them after running out of fuel but like Jim said be easy on the starter bc im sure they arent cheap.
