Fuel System Service

Common Fuel System Repairs:

  • Fuel pump replacement: The fuel pump delivers fuel from the tank to the engine. If it fails, the engine may not start, or it may stall while driving.
  • Fuel filter replacement: The fuel filter removes dirt and debris from the fuel before it enters the engine. If it becomes clogged, it can restrict fuel flow and cause engine performance issues.
  • Fuel injector cleaning or replacement: Fuel injectors deliver fuel to the engine in a fine mist. Over time, they can become clogged with debris, causing reduced engine performance or misfiring.
  • Fuel tank repair or replacement: Fuel tanks can rust or develop leaks, leading to fuel leaks or fuel system contamination.
  • Fuel pressure regulator replacement: The fuel pressure regulator maintains a consistent fuel pressure to the engine. If it fails, the engine may not start, or it may run poorly.

Diagnostics

Fuel system problems can be indicated by: rough idle, missing, running rough, exhaust smoke, poor performance, poor fuel economy, sputtering at high speeds or not starting at all. At Hi-Tech Car Care we have the equipment to access the trouble codes from your car’s computer and to diagnose problems with each fuel system component.

Fuel Injection

Fuel injectors are small electrically operated valves. They can become clogged or stuck open. Indications of fuel injector problems are: rough idle, missing, running rough, exhaust smoke, poor performance or poor fuel economy. Electrical maintenance is important for keeping your fuel injectors functioning properly.

Fuel Pumps

Modern automobiles have the fuel pump in the gas tank. This arrangement avoids the vapor lock that sometimes afflicted older cars. If a problem with the fuel pump is suspected, the fuel pump relay should be investigated first. If the fuel pump is faulty, it will have to be replaced, which involves removal of the fuel tank.

Fuel Filters

Many fuel system problems can be traced to a clogged fuel filter. Symptoms of a clogged filter are sputtering at high speed or not starting at sll. If the fuel filter is not functioning properly, it can let dirt particles through, which can lodge in the fuel injectors and cause them to stick open. The fuel filter should be replaced according to the manufacturer’s recommendation; usually every 30,000 miles.

Fuel System Flush

If you have contaminants in your fuel you may need a fuel system flush. The best way to avoid this problem is to buy your fuel from a service station that you trust.

We stand behind our workย and offer warranties on most parts (over 90%) and service for 3 years or 36,000 miles.
