perhaps time for spark plugs and wires. Hopefully not the coil packs.

Check the headlight relay, it may be defective or it has no power due to a shorted fuse. Refer to the owners manual for location, it will be under the hood most likely..

Test the voltage of new battery,Test voltage at starter connector with battery connected.12 volt is what you should get.-------Not always but sometimes new batteries and starter even comes weak or bad.-----------

It could be that the air conditioning compressor clutch is not working properly. The clutch should allow the pully to freewheel when the air conditioner is not used.
You can have your battery tested at.an auto parts store, and you can test the alternator by removing a battery cable while the engine is running. The alternator is what powers all the electrical systems while the engine is running. If the engine stops running when the cable is removed, this means that the engine was running from the battery and not the alternator.
Your alternator or your regulator is bad.
Regulators are an internal part of alternators, unless its a pre 70's.car where they were a separate external unit.
Hope this is helpful.

Check fuel pump fuse.

Should be in the fuse relay box in the engine compartment. Your owners manual should have details.

You'll need to know if it is spark or fuel related to proceed. Will it start using starting fluid ?

if security light is staying ur ignition key cylinder is worn out ,not the pcm needing reprogrammed

Very odd, but I was unable to find either of your codes. Check them again. Then go look up OBDII codes for your car.

Go under the car and see if you have 12 volts at the purple wire to the starter solenoid when the key is held to crank position, the wire may be broken or the starter solenoid is defective.

Yes. Go to the Pontiac Firebird/Trans Am owners forum and join it. You will be able to download manuals and get answers and tips about working on your car. Pontiac Firebird Trans Am Forum Pontiac Forums

It is tied into the pass-key system that disables your car as part of vehicle security. You would have to by pass the pass key system which would make it vulnerable to theft as any duplicate key or broken ignition could start the car. In my estimation if it ain;t broke don't fix it or you might wind up with an inoperable car. There is more than mechanics involved ...codes and software programmed into the bcm will disable the starter, pump and injectors.
