Does a Chevy Metro 2000 have power steering and if so where is it?

No, a 2000 Chevy Metro did *not* have power steering as standard equipment. It was an option, but not a common one. If your specific Metro *did* have power steering, the pump would be located in the engine compartment, likely driven by a belt from the crankshaft, but its precise location would vary slightly depending on engine specifics. You'd see a fairly substantial pump unit connected to the steering column via hydraulic lines. However, without seeing the vehicle, there's no way to be certain.
