I have a 2006 Ford Focus and I recently replaced the battery.
Everything comes on dashboard, lights, radio, etc. Then when I turn the key to ignition the lights kind of flicker and then nothing! Everything goes dead, I tried turning the key again after that happens and nothing all dead. After waiting a few minutes power returns or I have to disconnect and reconnect the battery to get power back. But I still have the same issue power back on, turn the key, all goes dead.
I tried jumping the car no luck nothing happens car will not start also replaced ignition relay thinking that was the problem. Nothing. Maybe the starter solenoid? a fuse? battery cables? ignition switch?
