Welcome to JUST ANSWER heavy equipment. With years of experience, I look forward to doing my best to help. Have you bleed the fuel system up to the injection pump? and then loosened the injector lines and cranked engine over to see if you have fuel to the injectors? Be sure the fuel shut off cable is in the run position and has not slipped at the injection pump. Do you get any smoke when cranking? No smoke, no fuel to the cylinders. The pump could be stuck internally and is not moved to the fuel open position. Let me know. Thank you.
