How does the fuel injection system work in a car?
When the engine is started for the first time at any given day the fuel rail which is part of the fuel injection system is pressurized by the fuel pump, under command of the engine management system to the operating pressure of the fuel injection system. This operating pressure is maintained throughout the driving or running period.
What are the different types of fuel injection?
There are two types of fuel injection systems, manifold fuel injection and direct fuel injection systems. The basic manifold fuel injection system consist of a fuel pump, fuel pressure regulator, fuel lines, fuel filter, fuel rail, fuel injectors and the engine control unit or engine management system.
What’s the fuel pressure of a direct fuel injection system?
Direct fuel injection systems operate at fuel pressures from 500 Psi at idle all the way up to 3000 Psi. Even thou fuel pressures are very high clogged fuel injectors does occur.
What kind of fuel injectors are used in a manifold?
Manifold fuel injection systems on average operate at about 45 Psi (Pounds per square inch) Side feed and top feed fuel injectors are used in manifold fuel injection systems.

This operating pressure is maintained throughout the driving or running period.
What happens when fuel injectors are not working?
The engine does not make power. Engine does not want to start. Clogged fuel injectors diagnostics. Diagnosing dead or clogged fuel injectors is difficult because it acts the same than a bad coil, dead spark plug, broken spark plug wires and or electrical problem.
