i have civic 2000 Vti around 190000km driven
now for the past month it has been giving me starting problem
Got it checked from Honda
they said its battery, got the battery changed
problem was still there
then they said its the self
got the self serviced and worked on by Honda charged 4k for that
after that it got a lil better for the time being but after 3 days it was back to same old
Now what happens is, when car is cold it starts easily on 1st self with no problem
Problem starts when in day time after driving for 1 hour or more with ac or even without ac
Basically when can engine gets hot
when I turn the car off, now when i try to start again it won't start and it gives sound as if self is stuck or battery is down
and then i have to wait for like 2 to 4 min before it starts again
For example if I go to market and park car after buying groceries when i come back the car won't start
so now for the past week I have been keeping my car start if i have to leave for few min and its really annoying
Other problem that happens is when this happens
all settings of PRE resets and also the clock resets 
can't understand what the problem is :S
