Injector colours
Asking for a friend (as I run a a Puma) He’s got a 130 TD5 it’s a T99, when bought it ran well & pulled hard. An injector went down ( years ago) & he had it fixed by an independent specialist.
Since then he’s had it in and out of numerous places as it lacks power & struggles up hill.
Earlier this week he discovered the injector that was changed is a different colour to the rest, would this make a difference or have any significance?
Thanks in advance.

Could do with a bit more information on the engine. It should be a 10P engine in a 99MY but do you know whether it still is a 10P engine or has had a replacement later 15P engine installed. Is the ECU an MSC (early) or NNN (later) ECU? Is the fuel feed internal (10P) or external (15P black hose under intake manifold)? It is possible to have a 10P block and a 15P head Frankenstein engine if it has been "upgraded" when a head died.

Blue/Black Injectors = Earlier 10P and MSC ECU 1500psi Short travel piston
Green Injectors = Later 15P and NNN ECU 1700psi Long travel piston

Whether a 10P or a 15P engine it should really be fitted with 5 injectors of the same colour.

What a wealth of information, many thanks for the in-depth reply. I’ve asked my friend for as much information he has & will post it up when I know more.
