My 02 glant won't start when it's warm..when it's cool I can start the car but after run...turn off and i can turn on again..i have to wait for at least 6 hours later...
The car not starting when warm can be a sign of a low charge in your battery. If it is more than 18 months old (usual warranty period), it could need replacement, since some of the cells are no longer functioning.
Warm starting gasoline engines sometimes needs a higher charge to start it up.

I have to ask, how long since a tune-up? Can you check for applicable trouble codes, if there are any?
Maybe it runs ok in open loop, open loop doesn't use the 02 signal until it warms up? Closed loop dies use the 02 signal. Changing the 02 sensor is part of a tune-up.
With idle issues, clean the throttle body and any small idle air passages. Check and clean the idle air valve. Check anything that has to do with air flow.
As with any no start issue you will need to figure out if you are dealing with a no spark or no fuel problem to proceed. Check the plugs for spark and the fuel pressure the next time it will not start. Could be a faulty relay, ignition module, coil or other electrical component. Let us know what you find.
I have a 1985 Camaro and if the switch for the fan is off then it overheats. There is a fan that can be installed. My switch is on the left of my steering wheel. Tune up is always good. Have your alternator checked, if it's old can be a problem maybe. New spark plugs can't go wrong. Good Luck!!!
give the engine a minute or two to cool down before turning it off. This cool down period allows oil to circulate and cool down the bearings in the turbo. If you shut off the engine immediately after hard driving, the oil can gum up around the hot bearings and create problems down the road.
Hope this helps
