Question about Cars & Trucks
The car start very well when engine is cold but as soon you stop the car when hot it wont start back unless you put the pedal to the floor
It sounds like you have a "flooding" problem, where you are getting too much fuel on the warm start. It takes more fuel to start a cold engine than a warm one. By holding the pedal the pedal to the floor, you are telling the computer to do a "clear flood" operation, and that lets you start the car. The culprit is probably the Coolant Temperature Sensor. If this is faulty, it will tell the computer that that the coolant (thus the engine) is much cooler than it really is. This results in the engine flooding when warm. It may also run rough at idle after warm start since it is still getting too much fuel. You will also notice a massive loss of fuel economy. Replace the coolant temperature sensor.

Local mechanic determined engine was flooded and started it by holding throttle to the floor and cranking 5-7 seconds - then the engine sputtered to life. It has run perfectly before and since and I'm at a bit of loss to understand why this occurred this one time - so far. It's been driven now 5 days with no problems.

Hi, it sounds like the starter solenoid was not wired properly. You have 2 wires at the starter, right? The bigger wire goes to the big top post on the solenoid, right? The smaller wire is called the start wire and it goes to the smaller terminal labeled "S." Is that how you wired it? You also have to be careful when tightening the nuts on the terminals that the start wire terminal does not touch the other terminals and vice versa. Do you have the starter in the car now? Can you take a picture to send me?

I have the same problem. When my dealer changed my coolant I now seem to have a stuck thermostat. They are denying they did it. I haven't changed the thermostat yet but that is the problem.

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.
