How do I check injectors? 1986 FC Non-Turbo
 

Trying to get my car road ready.

It wont start and Im trying to diagnose the car on my own first.

I want to know how to check the injectors to see if they work. Im new to this type of motor so any help is greaty appreciated.

although you can't get to the rear primary, listening through a flathead screwdriver or stethoscope works. They should click.

And do you have to have someone push the gas pedal to check for clicking? Since the car isn't running.
