About Fuel Injection Relays

The Toyota 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 Toyota 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 Toyota 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 Toyota fuel injection relay will guarantee you get the right component that's designed specifically for the make and model of your car.

Toyota trivia

  • Although Toyota started making its first cars in 1937, these were specifically produced to contribute to Japan's war effort. It wasn't until 1947 that they started producing cars for civilians.
  • They might be one of the biggest and well-known brand names in the world, but Toyota is still very much a family business. Every CEO so far has been a descendant of the original founder.
  • The founder's son, Kiichiro Toyoda, did a trip around the US to get inspiration for car designs. That's why those early Toyota cars look more than a little bit like Chevrolets and Dodge Power Wagons.
  • The Toyota Prius is just the latest example of why Toyota is widely considered the greenest company in the car industry. Consistent efforts at improving sustainability and eco-awareness led to them getting voted the number one Global Green Brand back in 2015.
  • As well as their other records, Toyota is known to consistently break sales records as well. It's not just the Corolla either. They have been so successful some years that they outsold Honda and Nissan combined!
