MY PUNCH IS IN THE TRUNK OF G35 INFINITI WHEN I TURN CAR OFF THE AMP IS STILL RUNNING AND DRAINING MY BATTERY I SEE A RED LIGHT ON THE AMP WHILE POWER IS OFF IN CAR

Presumably you had to disconnect the battery, so you have to reset the security system which also includes the anti-theft engine immobilizer. Solid red light means NATS/IVIS is triggered, the ECM will still CRANK the engine but it will not open the fuel injectors or deliver spark. You may need a mobile auto locksmith to program it.

Is your NATS/IVIS indicator LED solid red when cranking the engine? If so then yeah you probably just need to get it reprogrammed, or the RFID chip in the key failed. You can follow the troubleshooting steps in the FSM, section BL - Body/Locks/Security

You can not jump a dead battery

That is also an unsafe practice

Have to disconnect any battery that is
dead & try to charge it first or replace,
if it is over 4 to 5 years old & died

Sounds pretty simple. If your starter is not at fault. you may want to check the alternator. If the reason for the battery change originally was due to the battery dying then the alternator could be the culprit.

Borrow neighors jumper cables or swap battery with one from another car.
I am assming that the battery is in the engine compartment.

I had this problem on my 2004 G35x. I checked the trunk lock solenoid. It was OK. The trunk light was not working either. Turns out that there were three broken wires in the flexible harness between the trunk lid and the body of the car.

on the left side of the steering wheel. if you reach bellow in plain sight. there should be a few control switches. if i remember correctly there is there. there is one that says VTC. and to the left of the button. there is a switch. that is the trunk popper switch. slide the button down and it will open the trunk.

The wires that go from the body to the trunk lid are broken, the wires are located inside the rubber boot that connects between trunk and the car. very common problem.
