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.
