The screwdriver was merely a suggestion to help listen to the click by listening through the screwdriver. If you stick 12v of power to it, the injector should open up to spray gas hence the clicking sound of the solenoid. (I wouldn't just stick 12V on it, it could damage the coil from too much current. There are special service tools that have a cable and resistor, to limit current flow that you can use or you can try wiring a resistor of 100 ohms in series with it and see if gas flows out, that should be enough to protect it from damage.)

Using a long shank screwdriver, hold the screwdriver handle up to your ear, the long shank on the sensor itself, and you should be able to hear a clicking noise. If not, then it is probably either clogged or the circuit inside is open.

A stethescope will also work.

Fuso 6d40 injector pump didn't transfer fuel to injector.


bleed the air out of the pump
from your photo the bleed screw is the nut with a screw in it that has a slot. Use a flat bladed screw driver and loosen the screw and use the hand pump located in the photo right at the bottom and lightly to the rear of centre. Undo the top ,pump until you have solid fuel from the bleed screw and close of the bleed screw. Connect all the injector lines up leaving them loose at the injectors. Crank the motor and you will see ( after a few seconds drips of fuel at the loose nuts . Tighten the nuts while cranking and the engine will fire as the injectors start to work (SAFETY NOTE)
THE FUEL AT THE INJECTOR NUTS WILL BE AT 20.000 PSI OR BETTER SO KEEP YOUR FINGERS WELL AWAY FROM THE NUTS.AS YOU TIGHTEN THEM UP.

Check to see if all your fuel injectors are firing. To check, take a screw driver and press it agains the injector, then press your ear against the handle of the screw driver and listen for clicking. If no clicking, then either your injector is bad or you have a bad injector resistor pack. I'm not sure how to test the resistor pack (standing in front of the car, it's on the right side of the engine compartment with the heatsink attached), but you can check your injector by measuring the resistance on the contacts of the injector. You should get 1.5 - 2.5 ohms. If not in that range, that could be your problem. Next I'd think about replacing the ignitor inside the distributer and/or checking the fuel pressure to make sure it's good.
