I have done that several times and sometimes I even have to crank it over to get the horn shut off. I have not even locked the door since i got it. I have tried to start it many times. So I do not believe that is the issue. I feel like there is something wrong with the anti theft system.
I have an 05 Cobalt first off I have no power to my relay or fuse that runs the fuel pump. Also when i open my door the alarm goes off. not sure if the 2 are related or not. But I am new to the Cobalt I bought it as a non running car. Thank you for any advise that you can give me.
