i checked that the injectors were getting fuel, they are. i bled the fuel injection pump, it needed it. I Have checked the wires on the glow plugs, all snug. inside the glow plug light comes on and goes off after an interval. but, i am supposing that would not signal that the glow plugs are not working or would it? could it be a ground problem? but it doesn't seem to be firing. So a closer look at the glow plug system should be my next move i am guessing?
