Why does my diesel have a long crank when starting?

Why does my diesel have a long crank when starting?



Your long crank while starting your diesel could be from a couple of different reasons. If your diesel has glow plugs, then this could be the issue. Your glow plugs over time will wear out and stop working properly. Glow plugs unlike spark plugs do not have a maintenance interval. They do not have a maintenance interval because they are only used when starting the vehicle. When they start to fail you will have a longer than normal crank or your check engine light may come on. When you have a long crank, it is hard on your batteries and your starter. Over time it will shorten the life span of your batteries and starter. This will cause them to need to be replaced. Give us a call and let us take care of you.
