My '01 S60 (51K miles) has a curious hard start problem. If the engine is\ncold (as in overnight cold) or left for less than about 5 min, it'll fire\nright up. If left for more than about 5 min up to all day, it takes 5 to 10\nsec of cranking to get it to fire - sometimes longer but I'll shut it down\nand retry if goes too long. Once started, it runs fine and it's not\nthrowing any codes. The car is maintained by the book so the plugs (my\nfirst thought) are fairly new.\n\nAny pointers about where to start would be appreciated.
