P0193 can be due to disconnected fuel pressure sensor hose. It can also be caused by excessive cranking without engine starting so we should not worry about this as it is the injectors that are not working.
Lets try this.
With test light connected to injector RED wire.
Turn ignition on.
Test light should come on.
Test light shoudl remain on. If not, you have a ower supply interruption and it could be a faulty ignition switch.
Disconnect injector wireharness.
Attach noid light across the two terminals.
While cranking engine, the noid light should flash, if not, the PCM is not grounding the circuit.
