Engine Won't Start After Disconnecting Battery

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.

    yes and most likely.

    disconnect the battery without the key in at all, leave for an hour disconnected then reconnect. then try the key.

    if still dead check battery voltage is at least 12.0V. if thats ok, check all your fuses and relays, and if they are all ok (check both in cabin and under bonnet fuseboxes), you may have fried your immobiliser GEM :(

    Thank you for the reply....

    It turns out that I put one of the fuses back in the wrong spot (yes I know, I'm an idiot lol), after correcting this it worked perfectly.
