The ignition problems when a hot engine of used mitsubishi pickup is usually related to fuel.
When a hot engine of cars like Used Honda Accord is turned off and the temperature of the engine of used mitsubishi pickup and other parts continue to rise for a while so that the engine begins to experience a period called "heat saturation" . This causes boiling within the fuel chamber of the carburetor, fuel lines and fuel filter. When you try to restart the engine, the steam blocks the fuel flow and thus the engine will not ignite.
This problem is not very common in fuel injection engines because fuel is usually under high pressure in the injectors and lines. Still, a fuel line that is located near the muffler or exposed to too much heat can suffer the same kind of difficulties.
The heat saturation problems can usually be solved by wrapping the affected lines with insulation material and placing a heat shield or insulation under the carburetor.
Another reason why a vehicle is not turned on by winter or spring. In countries like the U.S. or Canada (does not apply in Mexico) refineries change the mix of fuels, for example in spring season occurs less volatile gasoline for the warm days of spring and summer so that the gasoline is less likely boil and cause ignition problems with the engine warm. While on the other side during the winter gasoline refineries switch to a more volatile because it allows easier ignition at low temperatures. If you happen to have in your petrol tank mix winter and spring begins, you can suffer problems on if the engine of toyota avensis is warm. The problem will end as soon as refineries make the switch to gasoline made for summer.
Moreover there are other circumstances are not very common but why not pledge when the engine is hot; between these causes may be that your vehicle has problems in the engine cooling which causes it is very hot (the pistons swell and rub the walls of the cylinders).
