That looks like the 12V supply to the injector is missing. 

Check at the injector plug you have a good 12V feed.

I would be testing the signal out of the ECU not at the injector plug. You would need to find a power source near the ECU tho. Then you can work out if it's a wiring issue.

I cut wire and connect directly to ecu, this osciloscopes makes from ecu. Problem is in ECU not in wiring, but Link repair service dont find it.

Have you checked to see if the is any damage to the ecu plug. Or best to power the ecu out of the car and join straight on ECU pins. 

The repair service has been good finding the issues ive had.

If ecu plug will have be damage we dont have any signal on osciloscope. But we have signal and have frequency of signal. I connect dirrectly to ecu and from cyl 1 2 4 we have good signal but from inj 3signal  wrong. Tell me why?
