Warning Signs of Fuel System Problems

Don't ignore these symptoms that indicate fuel system issues:

Performance Problems

  • Poor fuel economy – using more gas than normal
  • Loss of power – engine feels sluggish or weak
  • Hesitation or stumbling – lack of response when accelerating
  • Rough idle – engine runs unevenly at stops
  • Engine surging – RPMs fluctuate without input
  • Stalling – engine dies unexpectedly

Starting Issues

  • Hard starting – extended cranking before starting
  • Long crank time when hot – fuel pressure bleeding off
  • No start – fuel pump failure
  • Stalls immediately after starting – fuel delivery issue

Smells and Leaks

  • Gasoline smell – fuel leak or EVAP system failure
  • Visible fuel leak – wet spots under vehicle
  • Fuel smell from exhaust – running rich (too much fuel)

Warning Lights

  • Check engine light – fuel system codes detected
  • Reduced power mode – engine limiting performance

How Your Fuel System Works

Fuel Delivery

  • Fuel tank – stores fuel and houses the fuel pump
  • Fuel pump – delivers pressurized fuel to the engine
  • Fuel filter – removes contaminants from fuel
  • Fuel lines – carry fuel from tank to engine
  • Fuel rail – distributes fuel to injectors
  • Fuel pressure regulator – maintains proper fuel pressure

Fuel Injection

  • Fuel injectors – spray precise amounts of fuel into cylinders
  • Direct injection – injects fuel directly into combustion chamber
  • Port injection – injects fuel into intake ports

Engine Management (ECM/PCM)

The engine computer controls fuel delivery based on input from:

  • Mass airflow sensor (MAF) – measures incoming air
  • Manifold absolute pressure (MAP) – measures engine vacuum
  • Throttle position sensor – monitors accelerator input
  • Oxygen sensors – measure exhaust content for fuel trim
  • Coolant and air temperature sensors
  • Crankshaft and camshaft position sensors

Frequently Asked Questions

How often should I have fuel injector cleaning?

Most manufacturers recommend fuel system cleaning every 30,000-45,000 miles. If you notice performance issues or use lower-quality fuel, more frequent service may be beneficial.

Why is my check engine light on for a fuel system code?

Common causes include failing oxygen sensors, EVAP system leaks (often a loose gas cap), fuel mixture problems, or failing sensors. We diagnose the specific cause to recommend appropriate repairs.

Can bad fuel damage my engine?

Contaminated or old fuel can cause performance problems and damage fuel system components. If you suspect bad fuel, have it checked promptly. We can drain and flush the fuel system if needed.

Why did my fuel pump fail?

Common causes include running the tank low frequently (the fuel cools and lubricates the pump), contaminated fuel, and electrical issues. Some pumps simply wear out over time.

Is fuel injector cleaner from the store effective?

Over-the-counter additives provide minimal cleaning compared to professional service. For significant deposits, professional fuel injection cleaning is much more effective.
