• Whining Noise From the Fuel Tank.
• The Engine Sputters or Surges.
• Trouble Starting the Car.
• Loss of Power Under Load.
• Reduced Gas Mileage.
• Stalling at High Temperatures.

What causes fuel not getting to engine?

Clogged Fuel Injectors If the car cranks when you turn the key, but the engine won’t start, it could be because fuel isn’t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.

How bad fuel affects the engine?

Heavier fuel cuts can create combustion chamber deposits which will reduce the life of cylinder rings and liners. A low cetane number can also result in engine damage over time. If the cetane number of the fuel is low, engine knock and starting trouble can result from delayed ignition.

How do you diagnose a fuel problem?

A fuel system should be carefully tested for pressure, volume, and electrical integrity before condemning the fuel pump. Often the first step in diagnosing a faulty fuel system is to simply listen. Turn the ignition key to the run position and carefully listen for a slight humming sound coming from the fuel tank.

What causes fuel problems?
