It does not work 2 ° Cylinder

I suppose you have tried to change the injector of the 2nd cylinder for that of the third, for example, to see if something changes?

Let's see
has compression how much?

They regulated valves?

The injector works if

it receives injection pulse in the plug or connector corresponding to the injector 2? Wheel to test injection pulse .... Disconnect the OK injector connector

in the connector places an LED and that another person will start, at that time the LED has to turn on the LED
the circuit or line is fine, in case you do not turn on you have problems, mandatory workshop.
Check or change the jebe or rubber rings of the injector
