What do cause Injectors #1 , 3 , 5 to not work (Maxima 1995)?
Very often the injector connectors become corroded there is power on the injectors all the time moisture and time takes it toll. The engine control module grounds the injectors one at a time. Which leads me to think something shorted power to the injector grounds. I use a automotive tool called a noid light to test each injector connector and the resistance of the injectors with a OHM meter is around 12 ohms higher hot and lower cold. No open circuit injector will function properly. Older injectors are being killed off with ethanol in the fuel these days. I can manage that knock sensor job with out taking off the intake manifold with a 12mm wobble socket long extension and many years if skill. Also 1995 Maxima is a first year car that has issues with the engine harness near the passengers side shock tower. That is where wire harness flexes and wire breakage will cause lots of issues.

Bad injector harness?
Those cylinders are all on the same bank which gives me that impression.
You also did not test the CPS before changing it.
Ouch.
