Cummins ISC Diesel Engine-fuel system failure
The Cummins ISC Diesel Engine has an accumulator that supplies fuel to the electronic injectors. The problem here is the drive has shattered causing a no- run condition.
Mounted in-line with the accumulator housing is the fuel transfer pump and distributor body.
So no drive means no fuel supply which equals a non-running diesel engine. There were many fine fragments from this failure so we replaced the entire component.
This replacement is a big job especially on a school bus because of the limited access to the passenger side of the engine.
The accumulator is gear driven and also has a fuel pressure sensor and injection control valve attached to it's body.
The accumulator assembly is the mechanical workhorse on a Cummins ISC Diesel Engine.
