    Is the push/pull selenoid opening and closing the fuel rack? If the machine has been sitting for that many years the linkages could be froze.

    crack the fuel lines at the injector and turn it over, be sure there is fuel.. if there is unhook the glow plugs and huff it with ether and it should fire.. I would either drain the old fuel from the tank or dilute it with clean fuel if there's not much in it... After you get it running I would reccomend some fuel treatment the first few tankfuls..
