2. Fuel pump - Wikipedia

   en.wikipedia.org/wiki/Fuel_pump

   By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by itself (i.e. without oxygen present) isn't flammable, therefore surrounding the fuel pump by fuel reduces the risk of fire; In-tank fuel pumps are often part of an assembly consisting of the fuel pump, fuel strainer and fuel ...

3. Powertrain control module - Wikipedia

   en.wikipedia.org/wiki/Powertrain_control_module

   A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...

4. Engine control unit - Wikipedia

   en.wikipedia.org/wiki/Engine_control_unit

   An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.

5. Vapor lock - Wikipedia

   en.wikipedia.org/wiki/Vapor_lock

   Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.

6. Fuel starvation - Wikipedia

   en.wikipedia.org/wiki/Fuel_starvation

   British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. 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 ...

7. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.
