How can i cheuqe to see if my fuel injecters are working properly ?

Answer 1

you can check for resistance, you need a voltmeter set it to ohms unplug the injector and check across the pins.

If you have a missfire in one cylinder, you can move the injector to another cylinder, if the missfire moved to the other cylinder, you have a bad injector.

As far as spray pattern, it's suppost to look like a nice mist, I heard of technicians that will raise the injector with the fuel rails and crank the car to check spray pattern but I do not recommend this.
