About Fuel Injection Relays

The Mazda fuel injection relay basically acts as an ON/OFF voltage control switch, allowing an electric current to flow to the fuel injectors that supply fuel to the cylinders of the engine.

The Mazda fuel injection relay will be housed in the relay box, usually found underneath the dashboard. The relay connects to the car's battery, as well as connecting to the specific part that the relay is functioning, in this case the fuel injection pump.

In a diesel engine fuel injection is essential but petrol engines also have fuel injection systems. In a fuel injected engine, the electric fuel pump/fuel injector injection pump operates with a fuel injection relay, and works by spraying a light, high pressured mist of fuel from injectors into the chambers of the engine, controlled by the computerised control unit, which manages the timing of this process. The fuel injection relay opens and closes the contacts that provide voltage to the fuel pump/fuel injectors. The injectors are fitted close to the inlet manifold, one for each cylinder, and are all calibrated (adjusted) to equally spray a mist of fuel into the intake of each cylinder in a sequence controlled electronically, for the sequential firing of the engine. The overall result of this ensures the engine is working to its optimum, providing more power and fuel efficiency.

When you need to change the fuel injection relay, a good quality Mazda fuel injection relay will guarantee a part that fits well, performs properly and has a long service life. Relays can fail because of oxidisation, overheating or due to a faulty connection in the relay socket. Faults can occur with the electrical contacts, relay coil and wiring. The connections can overheat and corrode. If there is a problem with any of the relays in your car, the warning light should illuminate on the dashboard.  It's always a good idea to consult with your mechanic when fuel system problems strike, to make sure the correct fault has been indentified. It's important when replacing the fuel injection relay to buy a part that will be compatible with the make and model of your vehicle. Buying the Mazda fuel injection relay will guarantee you get the right component that's designed specifically for the make and model of your car.

Mazda trivia

• Mazda is the only Japanese car manufacturer not to be based in Tokyo. Instead, they work out of Hiroshima and were there when a nuclear bomb was dropped. The Mazda factories actually survived the atomic bomb thanks to a small mountain being in the way.
• Mazda is the only Japanese car manufacturer to have ever won the 24 Hours of Le Mans contest. They won in 1991 with the rotary-powered 787B, sending shockwaves throughout the racing community.
• The fastest RX-7 in the world is the Racing Beat Bonneville. It was clocked at 242mph, and with a modified 13G lump, it was expected to get up to 300mph.
• In 2010, 459 Mazda MX-5s all gathered at the UNESCO Zollverein World Heritage Site in Germany. This is the largest parade of Mazdas in the manufacturer's history.
• Mazda entered the US market in 1987 with its first production facility just outside of Detroit. Car company Ford then joined with Mazda at the facility, and the two car brands have been in a collaborative relationship ever since.
