yes it will but you will have to change the engine wiring harness over, or change the 7.3L glow plugs over to the 6.9L style and change the glow plug controller as well
fault starter/cable, faulty solenoid, faulty wiring harness, or undercharged battery.
if you are somewhat mech. capable you can build your own cheaper than trying to buy one
Check the glow plugs (ohms) and wiring for shorts
Fix it, or have it fixed. Have it diagnosed properly to know what needs fixing. The main possibilites are failed glow plugs, the glow plug harness could have issues or the glow plug controller.
by glow grid I am assuming you are thinking of glow plugs without more information its quite difficult to give an accurate answer Things to look at are- individual glow plugs have failed, with some working and some aren't all glow plugs have failed (due to faulty glow timer (stuck on)) all glow plugs are working (electrically) but aren't being used (faulty glow timer (stuck off)) other electrical problems causing above issues (short circuit wiring harness, open circuit wiring harness, faulty switches and/or relays) other mechanical issues causing hard starts (low compression/worn rings/valves) or other mechanical issues that a mechanic rather than an auto sparky like me would know more about
the dodge/ cummins engine does not have glow plugs
I imagine that if the light is blinking the engine most likely has a glow plug out. This can often be tested by removing the preheat harness from the time/relay and using a test light. Attach the clip of the test light to the positive connection of the vehicles battery. Then probe the terminal of each glow plug, you might have to remove insulators and things to get to them. The result, if it lights up its good, if it does not, replace.
You will need to remove both valve covers and electrical connectors from the valve cover gasket, fuel injectors, and glow plugs. It's one entire harness per side and is replaced as an assembly. Good luck.
It is important to have a diagram for a glow plug relay. The diagram can be found in book for the specific car, or online in car forums.
Some do. This feature is called afterglow. The diamond will glow briefly after removal of the light source. You can read more about this phenomenon, below.
they are under the valve covers
