If you're check engine light is on, if this is you're question, no you cant turn your key to read the codes. If we are on the same page, you have to have them read with the OBD-2 Meter.

when ever you replace ECM computer, you must take out your CHIP , to put it into your new ECM. did you do this ?????? if not your engine will not run ,even with GOD turning the key .
In my opinion, it's almost certainly the radio. Even when turned off, it is still alive managing a few other things (like chimes) until you exit the vehicle, and I suspect that part of the radio is faulty.
It means the car has not reached operating temp. The computer wants the engine a certain temp so it can go into "closed loop" where it fine tunes the fuel mix for optimum economy and emissions. If it cannot reach that temp it sets that code. You either have a low coolant level or a stuck open/missing thermostat.
Ignition keys relearn takes about 30 min to do. 30-Minute Learn
Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to
start the engine, then release the key to ON; the vehicle will not
start. 3. Observe the SECURITY tell tale light. After approximately 10
minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and
wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a
total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now
ready to relearn the Passlock Sensor Data Code and/or
passwords on the next ignition switch turn from OFF to CRANK Important:
Turn the Ignition Switch OFF. The vehicle learns the Passlock
Sensor Data Code and/or password on the next ignition switch transition
from OFF to CRANK. You must turn the ignition OFF before attempting to
start the vehicle. 6. Start the engine. The vehicle has now learned the
Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs
will self clear after 100 ignition cycles. Without a scan tool you may
have momentary starter interruptions while history clears itself.
