Hey guys My 05 3500 6spd with smarty keeps dieing randomly. 2 days a go it sat and idled for 30 min. jumped in stepped on the clutch and it died would not start and dash goes dead. to day I have grid heater lights on(grids not on) on dash also it sounds like it has a miss just ever so slightly ( maybe missing an injection cycle?) if you leave the key on and wait the gauges will start to work and it will start then as soon as you step on the clutch is like you turned it of lift pump is putting out 12psi had to limp it home last night was down on power and and had a knock tapping sound today it runs fine but has the faint miss and dies ? I sure could use a direction to go in
