My F 250 when I go to start it the glow plug light nand the engine light blinkes on and off ,it will not go out so I can start it . When the lights go out it will start and runn for a few moments then the lights start flashing and it quits and now it will not go out , and it will not start . I have checked glow plugs and injectors wireing fuel and new fuel filter , and I have replaced the IDM ?
