I have an 11 year old Fiat brava which has developed a problem when starting some times it starts no bother but other times it wont start but will bump start. Its not the battery as its just been replaced about a month ago. When i go to start it it takes a couple of turns for it to start but when its running its fine but after i have switched it off and its not run for an hour or so it wont start again it turns over but wont start unless i bump start it.It seems like its not getting a spark or that the fuel is running back or not coming up can it be any of those or do you have any suggetions on what it could be?
