In an internal combustion engine, fuel starvation is 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.
The term "fuel starvation" describes a situation where an internal combustion engine fails to function correctly because it lacks sufficient fuel. This can be attributed to various factors like blockage, vapor lock, water contamination, pump failure, or improper system operation.
