Car not quite running hot yet.

Your assumption would be probable! Sounds like the cooling system is being pressurised from the engine which is normally caused by blown head gasket! Is the water mixing with the oil?

It sounds like a coil problem or its vapor locking when it quits again pour cold water on the fuel line and the fuel pump to cool both if your car starts you have found the problem if it won't start try replacing the coil

will try to help. is the radiator leaking onto ground? when you open radiator cap with engine running[careful very hot] is the coolant moving around? if so, it's circulating. in otherwords it's doing what it's supposed to do. is temp. light or guage hot? check for low coolant level. running hot all the time? check for bad thermostat.with motor off! check for wobbly fan, move it back and forth by hand to see if it has any play at all, if it has play, possible bad water pump.. hope this helps and thank you for choosing fixya.com

there is a drain for the condensation. it outside on the firewall on the pass side, probably pretty low. its got a little rubber hose looking thing stickin out shove some wire up there and clean it out. it get plugged up and it fills the hvac box up with water and the cox is not water tite

It sounds like the ignition switch is bad or the wire to the run terminal on the switch is broke.

The ignition switch is hot on both the Start and Run terminals. Sounds like the Run side is dead.

My 2000 accent will stall only when hot and will not start till it cools down.

Start by flushing your coolant system, then refill with a quality coolant.
Run up to temperature and check again for level (when cool again)

Check that the radiator is getting really hot quite suddenly when running from cold, as this is the best way of checking thermostat operation.
When over a set temperature (check your manual) the fan should come on.
If it never does - troubleshoot the fan (temperature switch or sensor first, then fan on direct feed to see if it powers up ok)

water pump needs replacing. The temp sensor in the motor is reading way hot but since pump isn't truning not moving coolant around to heat air coming into vechile.

I have a feeling its your water pump not pumping coolant. Water pump is run by the crankshaft. So in essence, the water pump pumps coolant faster while the engine or crankshaft is running which is why the temp would go up while still. It may not be cranking now maybe because the water pump pulley may be bad not allowing the belt to move. So have your cooling system checked.

Possibly a crank sensor on or around the harmonic balancer, acts as a magnet like on an old buick. When you get the truck to fire up run it until she gets hot shut it and try to restart if no start continues try spraying starter fluid on the crank sensor itself. What happens is the sensor overheats and wont register that your cranking the engine. Spraying the starting fluid on the sensor will cool it dramaticlly enough for you to restart.
