The fuel pump is an essential piece of your car. Its function is to send gasoline from your tank to your engine fuel components. The fuel pump is usually electric and is located inside the fuel tank. It creates pressure in the fuel lines, pushing gas to the engine. This pressure raises the boiling point of gasoline. Signs Your Fuel Pump is Leaking Most fuel pumps have a hole in the bottom. When the fuel pump leaks, gas escapes from this hole to other parts of the car, causing an array of problems. A fuel leak will have a gasoline smell to it, which contains carbon monoxide and can be very dangerous when inhaled. Below are some common symptoms of a fuel pump leak: ●      Gasoline Smell: The fuel system in your car is sealed.

If your car runs on gasoline, it has spark plugs. (For diesel and electric vehicles, spark plugs aren’t used.) The way an engine runs is by delivering a spark to compressed fuel and air. This happens within four, six, or eight different cylinders, one spark plug for each cylinder. The spark plug receives voltage from the ignition system, allowing them to fire when the cylinder has maximum compression of air and fuel in it. The spark plug ignites the air in the cylinder, and the engine creates forward motion as a result of that explosion   6 Signs of Spark Plug Failure Spark plugs fire thousands of times a minute. Normally, they operate perfectly, allowing your engine to run smoothly. But eventually, after about 50,000 to 100,000 miles on average, you’ll encounter sp ... read more
