Hello, we can get a wiring diagram for you, make sure to check all the fuel injector connectors for any broken or loose pins inside the connectors, pin fitment issues can cause an open circuit effect if not making proper contact. I'll post further information in a couple minutes.
Something you can check if you have a multimeter is, with the key off, unplug the fuel injectors and check the resistance on the two pins of the injector itself, if its and open circuit inside the fuel injector you won't get any reading, the meter will read OL, most fuel injectors are 12-14 Ohms of resistance for standard port fuel injection.

Here is a quick test on checking for power on both wires by using a back probing pin to check each injector wire while still plugged in, if there is power on both wires with the key On, engine off, there is no need of a resistance test of the injector at this time, that would come next if there is power making it to the PCM on the control wire, meaning the injector may have shorted out and damaged the PCM, but usually the PCM will shut down the injector if it can detect excessive current flow and prevent a shorted injector from damaging the PCM driver that controls it.
