Hi, apologies if there is already an answer on here somewhere - but I couldnt find one...
I recently took the battery out of my Focus 1.8TDCI 2004 to charge it (as it wasnt starting and had all indications of flat battery, which appeared to be confirmed when the charger was connected).
But now the battery has been reinstalled the car still wont start. The glowplug light comes on but its never come on before so I dont see what can have happened to cause an issue with the plugs.
Any bright ideas anyone? I'm hoping its something simple and cheap to rectify?
Thanks in advance

cheers
