Can you explain why this would be problematic only when car has been sitting
in the hot weather (sun) and not in the morning?

Interesting thing is that when after cranking for few times it starts RPMs
are lower
then they should be (like 500) and then they in a 1-2 seconds increase to
1100-1300 (it is not cold out, in the morning it starts great and RPMs
immediately
jump to 1500) which I think is ok, and after another 1 second oil indicator
goes
off, and it is all working great after that.

BTW, I noticed that my distributor cap is cracked where screw is could that
be
any reason for poor starting.

Main relay is surely not the reason here because I tried another relay from
my
friends Civic and I experienced the same starting.

I think it is very important thing that it fails when sitting in hot sun it
is about
35 degrees C (95 degrees F). It starts ok when sitting in the shade, and it
starts ok in the morning. But when I have been driving it in the afternoon
and temperature outside has dropped in the evening (probably it hasn't
dropped much in degrees but no sun anymore) it still started poorely.

My theory is that fuel evaporizes in fuel lines and it needs a few cranks
for fuel to
reach the fuel rail, and everything goes ok when fuel reaches the rail.
What do you think about that?
