Hi I have a 2004 Ford Fiesta and i disconnected the battery to wire led lights into the boot. After reconnecting the battery the car now wont start. It will not turnover, the stereo still works but the dash doesn't appear as it normally would when the key is in position two. It appeared to me that it was as if the battery was flat but I have charged the battery and it still doesnt start. I believe i may have left the key in the ignition when disconnecting and reconnecting the battery (I read that this should not be done whilest trying to find a solution), is this true and if so has it caused the problem? Any help would be appreciated thank you.
