I was called to another garage to fix a 2005 300c chrysler with a v6 engine and an automatic transmission. The problems they noticed with the car was Hard or no start, no throttle response,battery and ESP light remaining ON, most times immediate stalling after starting however, if it doesn't stall there's a rough idle throughout idling as a result an old PCM was replaced with a new one however problem still persisted.
I did all system scan and saw a P0340, P2167, P2166, P2115, P2116, p0603 and more module codes like C2202, U0168, U1414, B1A25, etc.
Only DTC scan I got p0403, p0403, p0340, p0052, p0058
Please, how can I fix these problems?
The major problem is that whenever the red round light probably, the security light, if it remains ON, the car won't start at all however even if it does start by chance, the car would definitely stall immediately.
On the otherhand , if the red perhaps security light blinks and battery light goes off, it will have only hard starting but would definitely start. Firstly, how can I fix the security issue? The client said: "he doesn't want anything security in the car anymore." How should I proceed to disabling that security completely? It's because of that that made the engineer encourage them to get a new ECU.
Please🙏, help me with the repair procedure and also wiring diagram showing power distribution layout identification for the engine bay and rear fuses.

Well it sounds like a real POS Chrysler. I would start by seeing what's wrong with security system. You got to start with the root problem and work from there. That lights on there's a problem and if you don't have the ability to analyze and I theft systems you going to have to find a Chrysler expert with a dealer level computer to go through that whole system
Thank you so much sir for the guide! Please sir, could this have also been responsible for the cars problem? When I used my testlight and ground to the battery with ignition switch to the off position, I tested the fuses. However, 1 of the fuse actuated a particular relay. Thus, I pulled the relay out and tested it's circuit.
