Well I was having an issue with my cobalt with no lights turning on the dash what so ever and the car would not start. Went to the dealer. Took them a full week I guess the fuse box was bad and fried them rock and tcm. Got a new battery, a new fuse box, a new ecm, and a new tcm. Drove it home and to work. Took it to work the next day and half way there it started having all these signals go off at once “low fuel , power steering, ect” Even the security light turned on for the key. I turned it off and turned it back on and I got to work normally. Got to work fine but the check engine light stayed on. It drove normal. Tried to start it a day later and the engine will not crank at all please help. It’s a new engine as well
