Help-ran out of diesel, pumped -still will not start

First ran out of diesel, have pumped ,still would not start, then loosened injectors, still would not start.. then as triing to get it to start a click sound came as if battery had gone down.. jumed battery ..battery not the problem... so am told starter problem ....had taken off.. no starter problem. Cannot get the engine to turn over at all now it is like it is locked up.. This is a 300D 1978 diesel. The Car is strong running, i know it is not anything wrong like engine blown etc.. is there some trick to this i need to know about.. just cannot afford the Diesel Mechanic right now with work being slow these days. Any help will sure be appreciated. Sign me desperate,:-) Gina
