was out tonight driving around, turned off the engine came back to it a bit later to start it and it sounds like the starter motor is spinning. it doesnt turn the engine over atall. it bump starts first time tho. the first time it did it was last night but then it started second key turn so i didnt think anything of it. did it a couple more times but always started. now there is nothing. any chance as it gradually got colder its done something? any ideas as whats gone wrong as my dad says the starter motor never just packs up like that? :S
