The fuel injectors on a 2001 Pontiac Sunfire are located
on the intake manifold. They're generally mounted directly above the intake valves of each cylinder. To be more precise, you'd need to specify the engine (2.2L or 2.4L) as their exact placement might vary slightly between the two.
However, without removing parts like the intake manifold and other components, you likely won't be able to see them directly. A shop manual specific to your Sunfire's engine is recommended for precise location details and service information.
