)4 Maxima Cranks but wont Start

My 04 Maxima originally threw a code for cam sensor bank 1. I changed the sensor.. ( Have used multiple....OEM and aftermarket) no luck. if I unplug bank 1 it will start and run in limp mode. I have tried changing all the spark plugs, all of the coils, changed the crank sensor also, replaced the starter, checked the wiring harness for imperfections. I am at a loss. I was just driving it one day and it just acted like it died. I have an extra ECU I picked up from the junk yard but there is no point in throwing it in because I would have to program t to the key and I am not sure that it is the problem. It is not throwing any codes now. I also grabbed a PCMfrom the junk yard. Does anyone know if that has to be programmed as well? Any help would be greatly appreciated.

Hey there!
I’m no professional by any means. No hate please.
have you checked fuel pressure?
The cam sensor: have you tested the old sensor to see if it was the issue? If you run a new sensor and still nothing it may be what the sensor is reading. Like a rotational magnet of some sort.
My diagnosis for a crank no start is spark check, air check, and fuel check.

Check the ignition timing. Might be off.

are you sure you are replacing the sensor in bank#1? have you tried a non good sensor? ( not after market )
