Cant find out why injectors are not pulsing

There is an ijector driver box or resistor box that can fail.
To make sure this is the case. You can test the injector harness with a test light by sticking lead wires in the 2 connectrs on each injector connector, make sure they do not touch, and turn the car over and look for the light to come on. Also, make sure that a fuse is not to blame, check the under hood fuse box as if there is an injector relay or fuse, it is usually in there.
Hope this helps.
