Code P0010 car will not turn over

I started out a few weeks ago with code P0010, had to put in an engine control module. A day before I put the new ECM in the car, I started the car up. It took two key turns before the car started. First, try you hear a click, second try it started up. It was run so hard, I shut it down within forty five seconds. Mind you, before replacing the ECM, my car ran fine.
Replace my ECM came with codes I had to relearn the system. Codes: P0315-crankshaft not learned, P0602-control module programmer error, P02176-throttle not learned, U0109-lost communication with fuel pump control module A.

When using the scan tool, I do not see P0010 and U0109. (Those two no longer show up.) What I get now when I scan with the scan tool, are P0315, P602, P2126.

I go out the next day, turn the key I get nothing. Let it set, came back, put the key in the ignition, the only thing I could hear was clicking sound on each turn.

Could it be the starter? I have never had any problem with my car starting. No never. Never stalled or any thing of nature. I buy a new battery every two and half to three years, regular on the oil change, I try to keep up on it.

At this stage, I am getting no response for the car when key in the ignition and turning it.

Your position please, what can I do or just try?
