I changed thatFuel filter? With the engine not running - turn the key to the run position for about 5 seconds. Then turn it off. Then back on. Do that about 3 times. Then check your fuel pressure. Each time you turn the key on, it will run the pump for 2 or 3 seconds. See if that gets the pressure any higher. Not sure if a 97 needs 35psi or more like 50-55psi. It changed somewhere around that time.
If the pressure doesn’t come up that way, then i would think it’s probably the pump or filter.
Otherwise, check pressure with the engine running. If low, maybe fuel pressure regulator which you haven’t mentioned testing or replacing.

Copied straight from the tech library. Sounds like you have solid pressure if the 32PSI is with the engine idling. Lean codes could be a number of different things. I'd start with checking for vacuum leaks, as rusty said.
