Fuel injectors are controlled by electronic pulses from the vehicle’s electronic control module. Injector connectors secure the signal wires to each injector and make the electrical contact. Just like everything else under the hood, they are susceptible to wear and tear. Being very close to the cylinders, injector connectors are subjected to significant vibration, temperature, and chemical exposure.

We now have the hard to find Hayabusa male and female injector connectors as well as the new Toyota Tundra and Honda connectors. We also have 2003 to 2010
Duramax and Power Stroke Diesel injector connectors.

Over time the connection could become corroded or loose, and the fuel signals from the ECM may become weak or might not reliably get through to the injector.

If your engine is running rough, you notice a loss of power, or your engine engine idle seems to be erratic, one thing to check are the injector connectors. If your injector connectors show signs of aging such as cracks, warping or loose fit, these are indicators that they could need replacement. Take time to examine them closely. The good news is that while fuel injectors are fairly expensive, new injector connectors from Connectors Fast are very affordable.
