INTAKE MANIFOLD, FUEL INJECTORS

The intake manifolds of the Fiero were used on many GM cars with the exception of the upper manifold on the '85-88 V6. We have seen upper manifolds in salvage yards which appear very similar to the upper Fiero V6 manifold (without the engraving or decal marking) but do not know if they will exchange.

FUEL INJECTORS

'84-88 2.5L There is a single fuel injector in the throttle body of 2.5L Fiero engines. We are unaware if the injector can be replaced by itself. If the fuel injector is faulty, it may be easier to replace the entire throttle body with one from a donor Fiero.

'85-88 2.8L We do not have confirmation which cars have the same fuel injectors used in the 2.8L Fiero. We suspect that cars using the same center manifold may have the same injectors. See the Intake Manifold section for the 2.8L.

Cold Start Injector Tony Borbely reports that the cold start injector for the 2.8L V-6 is AC Delco Part No. 212-312 at a cost of $114. If you visit acdelco.com and use the "shop by part number" feature, you can find 61 other vehicles which use the same cold start injector. Tony also reports that the fuel rail to injector fuel tube (for the cold start injector) and seals are also listed on the AC Delco web site. It is likely these items are reported as "discontinued" by GM.
