2007 chevy cobalt lt

Currently doesnt run, my grandma bought it and 3 weeks later it quit running. I am told she drove it home and went to leave 3 hours later and it wouldnt do anything. I am a certified tech and i have replaced the starter due to it not engaging or anything and now i can jump the relay and it will engage and crank the engine over. I have hooked the scanner to the car and the pcm and bcm are not communicating. Replacing the pcm and bcm should fix the issue and they are on the cheaper side. Would make a great parts care or fix it and drive it. It ran and drove perfect until it quit starting. Miles are around the 160000. Im not 100% sure what the are but i know it is close to that. The interior will be put back together before purchase. Message me with any questions
