Thought I would just mention this after contunually reading posts these days about cars that just refuse to start, then the next day the thing fires up just fine. This has happened to me several times till I researched it and found the answer.
Modern unleaded fuel is full of very volatile chemicals in the mix including things like Benzene, Zylene, Toulene, and these evaporate very easily at low temparatures (Good for cold starts and fuel economy), but have some side effects.
The problem arises when for example the car has been sitting all day and is then started and moved a short distance like from the driveway to the garage or a round a dealer lot etc.
If the engine is not allowed to warm up, the spark plugs in the cold running engine are coated with both a fine layer of conductive carbon as well as moisture caused by the rapid evaporation of the new fuels we use these days, this conductive coating of the spark plugs sometimes results in a no start condition the next time you try start the engine.
The fix is easy, if the engine is started cold, then run it for at least three minutes before turning it off to allow the plugs to get hot enough to clean themselves.
