Why is my Cummins N14 CELECT Plus not grounded?
A common occurrence will happen when, for example, when the ECM shows a 111 or 343 code in an N-14 Celect Plus model. This means the ECM isn’t grounded to the injector. Usually this starts out with only 1 injector shown to be malfunctioning but can quickly spread to others.

What’s the difference between the Cummins 855 and N14?
Overall, the biggest structural difference between the 855 and N14 is the air-to-air cooling system changes but both engines are very similar. The N-14 was produced until 2001 and saw many changes over its 10+ year run for Cummins. The most radical change over the 855 was the incorporation of the electronic control module (ECM).
What kind of fuel system does Cummins N14 use?
The N14 Celect was the first Cummins engine to feature an electronic injection system. The Celect fuel system produces systematic pressure throughout each injection cycle unlike the common rail fuel system of the 855, or older M11 or L10 models. Albeit the injectors are still cam actuated the ECM controls the metered flow of fuel to the injectors.
How often should the oil filter be replaced on a Cummins N14?
It is recommended that the oil filter, fuel filter and coolant filters all be replaced every 11,500 miles. The N-14 does not do well with cheaper filters that don’t further remove particulate matter.
