 Fuel starvation

In an internal combustion engine, fuel starvation is defined as the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading to loss of power or engine stoppage.Fuel exhaustion (also called "fuel depletion") is defined instead as an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation.
