Locating a vac leak by ear can be difficult at best. Using a mechanic's stethoscope w/funnel amplifier makes the job a lot easier. The spray test mentioned above by turtleman is another tried/true method that works.

If you can't find a vac leak, I would inspect the MAFF sensor and IAT (intake air) sensor for proper connection, dirt, or damage.

I would advise getting the Delco or Delphi pump.  It is a little more expensive, but it will last.  

Some of the cheaper units don't last very long, so in the end the savings aren't really there as you'll be changing it again soon... maybe very soon. Also go ahead and buy a new locking ring and gasket for $5-ish.  Most are corroded by now.  Cheap insurance.

I just did this replacement about 6 months ago, and it was a snap. I think it took maybe an hour. Be prepared to cut and attach a new wiring harness connector at the pump though. They changed the connector at some point. The new pumps come with the new plug, wire and instructions. It is easy, but is the only "complex" (not really) part of the replacement that isn't purely plug-and-play.

If your locking ring is really corroded, that can be a bear. Mine was pretty clean and still took some serious whacks with a mallet. But once it started turning, it came right off.

Well now that's a rarity. Not often does a Fuel Pump take a dump and toss a lean code out.

Glad to hear that it's fixed.

Lesson learned - it's worth checking fuel pressure as well when you have a lean code!
