WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
An 8-digit part identification number is on a mylar label affixed to the fuel meter body. Refer to this number if servicing or part replacement is required.
- Remove the upper intake manifold. Refer to Intake Manifold Replacement - Upper in Engine Mechanical-4.3L.
- Remove and discard the fuel meter body seal.
- Before removal, clean the fuel meter body with a spray type engine cleaner, such as GM X-30A, or equivalent, if necessary. Follow the package instructions. Do not soak the fuel meter body in liquid cleaning solvent.
- Remove the injectors from the lower intake manifold bores.
Lightly pull on the injector tube and using a small pocket screwdriver, remove the injector from the manifold.
- Remove the MFI (multi-port flexible injection) fuel meter body from the MFI bracket
NOTE:
Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage fuel system components.
NOTE:
Cover the injector sockets in order to prevent dirt and other contaminants from entering the open fuel passages.
IMPORTANT:
When disconnecting the injectors, remember the sequence in order to ensure correct injector placement to each cylinder.
