hello i have a 2004 clio 172 it has done 70000 miles it was running fine until last week when it wouldn't start firstly i thought it was the starter motor however when it was looked at we realised it wasn't. it turns over but wont start and all the power seems to be dying! we bumped it and it ran ok But then the warning lights started coming on and now it wont even Bump! it seems like there is no power even with a charger it wont start! would this be an immobiliser problem or could it be the ecu? i don't really have any knowledge about these things advice would be greatly appreciated thanks
