So I got my first Cummins and it is definitely a learning curve...it’s a 2006 5.9l I started it on a cold morning about 25degrees out I let it run for about 5 mins (obviously not long enough) but I put it in gear and started driving down my hill and it just shut off and would not start. I notice the grid heater smoking on the hot wire side. I replaced that but it’s still doing it?? And still no start I’m getting fuel to the injectors I’m just not sure if it’s enough pressure? I’m a one man band and kinda Ill equipped. how do I tell if I’m getting enough fuel pressure and if it’s too low what are common problems
