I just installed the zzp powerlog for my 2003 monte carlo ss. After installing it, I have a problem. My car will not start. I got in it and my stereo and lights and gauges work, but when I attempt to start it, it makes a clicking sound and the display says service traction system, service engine soon, and the radio display says cal. error... Does anybody have any advice or know what might be wrong?

 

just guessing, you pulled the cable from the PCM, and might have a bad connection. The drivers side is close to the cable, if I'm not mistaken. I have the powerlog myself, and had no issues. It's raining now, and the Monte is outside, so I can't check it now.
Make sure your battery connection is good and clean, also. The cal' error is the one that bothers me. The others are normal cuz the motor isn't running
