new guyhello! new guy here and off and running the car is a 2006 cobalt ls with 72k, 2.2/auto. the dash lights up when you turn the ignition and the starter will not crank. the security icon goes out as normal, i can go to the fuse box under the hood and jump the starter relay then engine will crank over. this vehicle was purchased this way and i noticed another bcm sitting in the back seat and have no idea if it has been switched. i checked all fuses in the bcm and they are good. not sure where to start? the ignition switch maybe? i do have another 2006 cobalt 2.2/auto 150K that purrs like a kitten but is wrecked in the front i can use for parts, like switching computer,ignition switch.... and i do about the key relearn as my daily is a 2005 saturn ion. i realize these cars are ridden with issues and just need some ideas. thanks guys in advance here with 2006 cobalt that doesn't run.
