Toyota Matrix Fuel Rail Parts Questions & Answers

• Q: How to replace fuel injectors and Fuel Rail in a Toyota Matrix?

  A: Relieve the fuel pressure and disconnect the cable from the negative terminal of the battery. Detach the PCV hose from the valve cover and remove the engine cover. Disconnect the electrical connectors from the fuel injectors. Open the wiring harness clamps and position the wiring harness aside. Disconnect the fuel line leading to the fuel rail. Remove the fuel rail mounting bolts and carefully withdraw the fuel rail and injectors from the cylinder head. Replace the 0-ring and grommet on each injector. Remove the insulators in the cylinder head and replace them with new ones. Lubricate the 0-rings with clean engine oil and install the fuel injectors onto the fuel rail. Make sure the spacers are in place and install the fuel rail/injector assembly onto the cylinder head. Install the fuel rail mounting bolts and tighten the belts securely. The remainder of installation is the reverse of removal.
