2016 ISX15 Cummins Fuel issue?

[tree98]

Why did he replace the entire pump?? EXACTLY what happened to the pump?? When these pumps fail they send metal debris throughout the entire engine.

The only way to save the engine is if you catch it early(like within a couple hundred miles of failure) and then flush the engine out numerous times with a mixture of diesel and engine oil, change all the bearings, probably the injectors too.

If your pump failed completely and all that guy did was put a new pump on and sent you down the road....... your engine might literally be a boat anchor at this point since you have continued to drive it and push metal fragments all through the oil circuits.

This is a very well known issue with the common rail ISX's. The high pressure fuel pumps need to be rebuilt every 400k miles to avoid these problems.
