I am sorry the fuel injector it was stock on like spraying all the time constenle and it did not pulse I change the injector and it stop working I put it in another injector and it those work so I check the volts coming and it reads 13 and it moves just a little and the other ones have like 13volts but they pulse from 13 to like12.56 volts I took the car to the dealer and they toll me to check for pinch wire I took the car home check all the wires I found one pinch wire fix it and still the same so I was thinking it was a pcm problem

You need to test that signal at the plug using a noid light. The computer pulses the ground signal but you can damage the computer if you test it with anything else.

Most any tool supplier carries them. They are sold either is set for various makes or sold individually for less than $10.
