From your initial description, it's hard to say.
Removing the serpentine belt was a good first move as this eliminates several parts.
What you have left is the vacuum pump, fuel lift pump and/or something internal (cam shaft etc) which is, I guess, your next point of examination.
How is the oil level ?
Lest us know what you find.

Im assuming you mean longitudinal play, rather than rotational play, as it will be keyed away.
Does the manual lever on the fuel lift pump still feel like it should do? I have a (real life) friend whos lift pump managed to shed its internal arm into the sump somewhere. Although manipulating the external arm probably wouldn't give indication of this, but its worth a go.
Cam is on that side of the engine, but id imagine that errors there would show up as valve clearence issues instantly, but youve looked at them.
