My Dodge diesel 6.7 was running good and when I came home from work, shut off and 2 hours later I went to start and the engine turns over, but will not start. I thought it was a fuel problem, so loosen injector and turned over and had fuel. I tried to run engine analyses and nothing. It appears there the electrical has shut down, but the engine still turns over. Are the fuel injectors electrically pulsed or by pressure form pump? The only thing that come up is check gauges. No engine light at all.
Turned truck off and about 2 hours later, tried to start and the engine turned over, but would not fire up. I checked to make sure it had fuel at the injectors and it did. Are the injectors controlled by electrical pulse or by fuel pump pressure? The only thing that show a problem is when you turn key on a check gauges light comes on. Engine turns over, but will not fire up. This a Dodge 2007 6.7 diesel with 187,400 miles on truck. Clean air filter, oil level is good. Ran engine analyses and could not gat any reading.
This can be caused by weak battery in your diesel,check them first,have seen them do this,even thoe truck turns good,it still want crank,if batterys are good,check the glow plugs.
