This method requires some experience and knowledge of fuel injection systems and access to the appropriate tools.

Tools required for this method:

This method requires the fuel rail, all injectors, and throttle body Remove the You may also need to remove the intake manifold to access the fuel injectors.

This method is time consuming and requires a lot of disassembly, but it is thorough.

Steps for this method:

Make sure the motor is cool to the touch. Remove negative battery. This avoids electrical problems when working with fuel injection systems.

• Remove the plastic engine cover using a suitable socket wrench. Set the cover aside.
• Remove the bolt and bracket holding the fuel rail with bushing and ratchet. The fuel rail is a metal rod that runs over the fuel injectors.
• Some models require the fuel line to be disconnected from the fuel rail before moving the rail. Have a rag or other cloth on hand to catch any fuel that may spill.
