Theft lock 2005 Cobalt

I have a 2005 Chevrolet Cobalt, I had to replace the Body Control Module as it got wet and shorted out. (Light flood) The radio is locked which is one problem, but the biggest issue is that I believe that the Theft Lock feature will not allow the car to start. Everything other that the radio works fine, the ignition seems to work fine, but when I turn the key to start the car, it does not crank and the security lock light comes on in the dash. The battery is fully charged, and I can jump across the starter and the engine will crank fine. It might have been a mistake, but I tried using a remote start button on the starter while the key was on, the engine would start run about 10 seconds and die.

Any ideas??

If the BCM has been replaced, the BCM has to be reprogrammed by a dealer as it control many car functions.

Could be a dirty throttle body, faulty idle control valve, or a vac leak. Usually if the idle control valve fails the check engine light will come on.

That code dsoesn't 100% mean the sensor is defective, other factors can set it. See list below.
Possible causes- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit

Where is a power steering pump located on a 4 cylinder chevy cobalt ls


Your Cobalt is not equiooed with a Power Steering Pump. It has electric power steering. See the description below.

Power Steering - System Description and Operation
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

No lights


check the park lamp relay and the body control module for possible causes. the body control module controls both systems.

Remote keyless entry, radio and power sliding door


I think the body control module is shorting out . The body control module can be over heating internally then shorted out. All the parts you mention have a circuit running to the body control module. I would have the vehicle checked for codes at a repair shop , then check the wiring to the body control module.
good luck
