How do you trouble shoot a Cummins diesel N14?

Answer by  MechMan3 (885)

You need to find out if its a fuel issue, air issue, or compression issue. A good shop should be able to bench test the injectors.

This is not something that can be done easily at home in your garage. A special diagnostic computer is needed which can usually be found at a professional mechanic's.

The easiest way to solve a vague problem like that is to purchase a Chilton manual from your local auto parts store. It has troubleshooting steps.

You need to hook your engine up to a diagnostic computer and see what codes come up on that. Once you have the codes get them checked out for meaning.
