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

Sounds like a starter motor issue if you want my two cents. Can't
really explain the whole cold start works, semi-cold start doesn't
scenario, but could be related to moisture in the distributor as well.
Did the problem start shortly after the plugs were replaced? I'd look
at them and make sure there's not condensate getting in some where.

Thanks for the reply but I doubt there's an issue w/ the starter. It began
some time after the plugs were replaced and I'm not sure about the
condensation idea as it's been going on all summer in hot, old Wash. D.C. so
it wasn't favorable to condensation.

Try this: When you think it is going to be a hard start, turn the key
to PII and wait about three seconds. Turn to PI, then back to PII for
three second then turn to PIII to start. This will "boost' the fuel
pressure in the system. If that is the cure, then there is a problem
with the fuel system not holding pressure.

I, too, thought it might be the fuel pump check valve so I tried that little
trick to no avail. This was the prime culprit except it starts OK when
cold.

Could be electrical. The symptoms suggest a poor connection that comes and
goes with heat/humidity. Start with the fuse box. Pull the fuses and check
them to see if there's any sign of corrosion. If so, replace all of the
fuses.
I struggled with a similar problem for some weeks until, by chance, I
wiggled a fuse in its socket and the car started.

Perhaps you had the wrong plugs installed.

And in keeping with the electrical theme, it could be the ignition
switch. I have seen wonky ignition switches that will crank but in the
P-III position the ignition contacts get disengaged so the ignition is
not getting current. I am not sure if that is possible with your car
or not, but it might be worth checking out. Maybe find the ignition
feed that goes from the switch and put an LED on the line so you can
see if it stays hot when cranking.
