The solenoid only controls timing

@douro20 You are correct about this system being similar to the old PT fuel system but, the injector is not OPENED by the electric solenoid. It is opened by the camshaft. The solenoid only cotro

Very well explained instructional video! I know nothing about diodes so I was wondering if you could tell me where I can get those and what I'm asking for? Thanks!

The system isn't that much different from the old PT system- the only real difference is that the injectors are opened electronically.

With this particular injector the way it works is that the solenoid is in an always open position allowing fuel from the rail into the injector and only closes during the downward stroke of the metering plunger so as not to allow the fuel to go back to the rail, rather trapping it in the injector and metering it to the cylinder. Technically, with this particular injector it would be more that the injector fuel supply is “closed” electronically at the injector.

[danielresume]

The solenoid is the only aspect of this injector that is electronic and governed by the ECM. It has been my experience that when these solenoids get weak or fail completely the engine might still run at idle without a misfire but under power will miss and have no power. The injector also has a ceramic check ball and metering plunger which will cause the same condition under power if worn as they will allow fuel to escape under pressure rather than injecting to the cylinder.

I love smelling the exhaust from an N14 also (0:25),the more you can inhale,the better it is for you. It's kind of like taking a multi-vitamin every day! Keep on trucking!

ZGreat job wish more would watch this instead of blaming other things. I work offshore and gained some insight into deisel engines from this myself.
