Hi everyone I’m new to this forum. I recently bought an accident damaged citroen c5. The car only needed paintwork and a wing mirror. However the car doesn’t seem to want to start, I assumed this would be due to the fact its been left standing for a while. The battery was flat so I recharged it at home. I’ve replaced the starter motor and still no luck. It ticks over but doesn’t start. Can anyone shed some light on this or if anyone has experienced something similar. Any help would be greatly appreciated. Thank you
