FUEL SYSTEM: What affects it and the resulting issues

You car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Typical Wear and Tear
Intervals for fuel system maintenance may be influenced by:

  • Fuel quality
  • Vehicle age
  • Mileage/time
  • Operating conditions
  • Maintenance history

Symptoms

  • Poor fuel economy
  • Vehicle won’t start
  • “Check Engine” light is illuminated

BRAKE SYSTEM: What affects it and resulting symptoms

What is it?
Your car’s brake system is its most critical safety system and you should check it immediately if you suspect any problems. A properly operating brake system helps ensure safe vehicle control and operation under a wide variety of conditions.

What does it do?
When you push the brake pedal, the force generates hydraulic pressure in the master cylinder. This pressure flows through the hydraulic lines and hoses to the wheel cylinders and calipers, forcing the shoes against the drums (drum brakes) and the pads against the rotors (disc brakes). The resulting friction slows the vehicle and is relative to the amount of force applied at the brake pedal.

Typical Wear and Tear
Brakes are a normal wear item for any car and eventually they’re going to need replacement. Avoid letting your brakes get to the “metal-to-metal” point, which usually means rotor or drum replacement. Factors that affect wear include driving habits and quality of brake pads and shoes.

Symptoms

  • Car pulls to one side during braking
  • Pulsating brake pedal or steering wheel shake
  • Brake pedal feels “mushy”
  • Unusual noise when you step on the brake pedal
  • Repeatedly need to add brake fluid to the master cylinder
  • Brake fluid sprayed onto outside of wheel
  • Unusual odor or noise
