When did Cummins come out with the N14 engine?

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).
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.

How does CELECT fuel system work on Cummins N14?
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.
Why does my N14 start only half full?
It’s normal for a clean N14 fuel filter to run at only half full so don’t worry about that. The easiest way to diagnose this problem is to install a guage on the fuel pump and watch the pressure as you crank the engine. Most likely the engine will start as soon as the pump builds pressure.
Is the N14 CELECT in T2000 cranks forever?
The N14 Celect in our T2000 cranked forever before it would start when I first got into it a couple years ago. After a month of the BS, I went and had batteries tested. Bad battery, so I put four new ones in. Still cranked ten seconds then would start.

What’s the difference between the Cummins N14 and ISX15?
The two engines are physically different in size. Two versions of the ISX were involved in the phase out of the N14 and the M11 (the little brother of the N14, which was likewise unable to meet emissions standards), the ISX12 and the ISX15. Because of the shift to electronic controls, the N14 has more valve train components than the ISX.
