hi all. here's a tricky one. my 2006 citroen xsara picasso has a start problem. it will start and run perfectly time after time then as soon as i plug the sat nav or phone charger or anything else into the cigarette lighter i have problems. the car will continue to run but as soon as i stop the car it wont start again. all i get when i turn the key is a click, the engine wont turn over at all just a click then i have to bump start the car to get it going, once i bump it it will start every time again. can anyone help??
