After is hot if I turn it off it would not start until is cool

check electronic spark unit ie coil pack going open circuit when hot
will run but when turned off will stay open circuit untill cools down then closed circuit then will wprk fine

If you mean that it starts fine when cold, but if you stop & turn off the engine (to to pop into a shop for example) then try to restart and get absolutely no turning over, then you need to replace your battery. It has a short or crack which is expanding when hot creating your problem.

I had a similar problem. my 99 taurus wouldn't start after it was hot until engine cooled down enough. It turned out that it was the fuel pump. It provided enough pressure when the engine was cool but as it heated up, the pressure would decrease. Then the engine was not getting enough fuel to even start.

Also, consider seriously about replacing the water pump. I have a friend with this exact car, and they had the same problem - the water pump was literally "gone" - when it was pulled and shown to me, I was amazed at the condition - this was the factory water pump and if you can picture what fan blades look like, imagine the fan without the complete blades - they were completely corroded and the pump was seized up - make sure you drive as little as possibe, as this friend had driven on it with the pump in that condition for months, which in turn caused a blown head gasket as well as several other mechanical problems.

After you kill it, when you try to start it back up, does the starter turn the motor? Or is it froze up (will not turn over)?

Hi.. I had a very similar problem recoverrd to are workshop by the A.A around a month ago.
Exactly the same problem (left to cool started.? Once worm or hot engine just turning over ?)
Afdter reading all known folts and finding nothing to do with what I'd wanted. It took some time ?
Cutting it sort if found when I replaced a intermittent faulty fuel relay and run till engine hot (untill cooling fan cut in) Then turned off engine .. on turning key to see if this had cured my problem?
The engine started frist turn of key after repeating this a number of times .. this car was now starting fine (whether hot or cold)
Problem fixed..
Hopefully this will be of some help to yourselves

I think its a cooling fan relay. Replace it and should be fine. Or a faulty temp sensor. But I bet its the relay.

sounds like the starter to me

I HAVE A 1998 CADILLAC DEVILLE,THE AC BLOWER MOTOR GETS HOT AND TURN OFF AND WONT TURN BACK ON UNTIL IT COOL OFF, WHAT IS THIS PROBLEM?
