I don't know nothig about you machine but have you check the basic? If electric fuel lift pump>make sure theres no air leak before the pump and check flow after pump, if injection pump is totaly mechanic check oil leve if above normal suspect seals at injection pump also if shut off valve is not stuck half way, disconect return line after last injector if good flow= injection pump ok, check air intake no restrictions, some times trash gets in the lines from injection pump to injectors or/ and lift pump to injection pump, also check for restrictions after hydraulic pump if direct drive by the engine this my keep it from turning rigth. hope this help u, u may want to ask for Mrkobelco he supoust to be a kobelco tech with accses to info
Thanks lineman,are 150 does not have a electric liftpump,air intake is clear,i tried also with the turbo air intake disconected,its a mecanical fuelpump but it has a electric stepmotor.Fuelflow from the tank is unrestricted.i can idle up and the RPM goes up without problems but as soon as there is any load,the motor bogs down and smokes black,i suspect it could be the step motor,will have a guy help me today to check on that.I dont know if the digital panel has anything to do with it but its blank since a couple of weeks.
