i have the excact same problem.. turn the key and it wont even try to turn the starter as soon as connected to jump leads and another car starts first time then fine after that.. leave over night and the same problem.. even does it if i disconnect the battery overnight tho so cant be draining the battery which is new.. even changed the starter and alternator.. its like it needs the extra power just to turn the starter then is fine after that.. hope someone has fixed this prob before...?
