Fuel pump sounds fine. It only comes on with the key in the "On' or 'Run' positions.
With the engine running, spray carburetor cleaner along all vacuum lines, around the throttle body, along the airbox and inlet hoses, and where the intake manifold meets the head. That'll tell you about vacuum leaks.
Make sure the air filter is clean and the air inlet isn't obstructed.
A lean condition can be caused by a faulty or overly dirty fuel injector. Having sat for 21 months, the varnish that builds up on injectors could have hardened to an extreme point. Run a couple of bottles of quality fuel system cleaner (my favorite is Techron), through the fuel system.
With the engine cool, feel around the exhaust manifold to head mating area for leaks with the engine running. Also checks for leaks in the exhaust flanges before the O2 sensor.
Other than the odor, how does it run?
