Fuel Injection
Fuel injection is a modern system that delivers fuel to car engines. It replaced older carburetor systems and is now standard in all modern vehicles. Think of it as the car's fuel delivery system - like a precise measuring cup that ensures the engine gets exactly the right amount of fuel it needs at the right time. Mechanics work with fuel injection systems regularly, as they need maintenance, diagnostics, and occasional repairs. This technology helps cars run more efficiently, produce fewer emissions, and perform better overall. When you see this term on a resume, it indicates the person has experience working with modern vehicle fuel systems.

Example Interview Questions
Senior Level Questions
Q: How would you diagnose a car that runs rough and has a check engine light related to fuel trim?
Expected Answer: A senior technician should explain checking fuel pressure, inspecting sensors, using diagnostic tools to read data, and following a systematic approach to isolate the problem. They should mention checking oxygen sensors, mass air flow sensors, and fuel pressure regulators.
Q: What experience do you have training junior technicians on fuel injection diagnosis?
Expected Answer: Should discuss mentoring experience, creating training programs, and teaching diagnostic procedures. Should emphasize patient explanation of complex systems in simple terms.
Mid Level Questions
Q: What tools do you use to test fuel injection systems?
Expected Answer: Should mention scan tools, fuel pressure gauges, multimeters, and explain basic testing procedures. Should know how to interpret readings and identify common problems.
Q: Explain the difference between direct injection and port injection.
Expected Answer: Should be able to explain in simple terms how these systems differ, their advantages, and common issues with each type.
Junior Level Questions
Q: What are the basic components of a fuel injection system?
Expected Answer: Should identify main parts like injectors, fuel pump, fuel rail, and pressure regulator. Basic understanding of how these parts work together.
Q: What safety precautions do you take when working with fuel systems?
Expected Answer: Should demonstrate knowledge of basic safety procedures like relieving fuel pressure, proper ventilation, and fire safety measures.
