Default Detroit Diesel (DD671N) Questions

RW Salnick wrote:

Wayne, when the engine is in the "hard to start condition", and then it
finally starts, does it do so on all cylinders, or does it go thru a
period where only 1, 2, 3, etc cylinders are firing for a while before
all 6 finally kick in? This could indicate a very slow leak between the
injection pump and the injectors.

DD671's don't have an Injection Pump. They have a Fuel Pump that
supplies a common Fuel Rail, to which each Injector tapes off of.
Each individual Injector is then pumped via the Injection Lobes
of the Camshaft. Remember this is a 2 Cycle Diesel, not a 4 Cycle.
