testing fuel injectors

I remember seeing on here the specs and how to test fuel injectors. I should of bookmarked it cuz i can't find it again. I'm wondering if someone can tell me how to test my fuel injectors with digital mutimeter. I put a screw driver on them and listen to em while the car is running and I can hear them all clicking except one. I'm thinking the one I can't hear might be bad.....and they are all the original injectors and probably could use replacing.
Also.....where is a good place to order injectors from. I have an 88 with the 2.8 liter MPFI.

Re: testing fuel injectors

Measure the resistance of each one. Should be around 13 ohms give or take and all very close in value. Southbayfuelinjectors.com sells a reman set. They are a TGO sponsor and you'll get 10% discount.
