Truck overheated, sounds like no compression now

Yes. Every time I put something back together that's had a top end or more apart to get oil back up top before I fire it. This is standard procedure, not just for me.
No, it doesn't crank faster because there is no rail pressure. If wetting down the cylinder walls with a bit of fuel makes your truck crank slower, your rings are toast.

That's partial firing due to insufficient fuel. With no fuel it would crank at just the same speed as with no spark. You need both (or lowered compression) to make it crank any faster.

No fuel is very different from an inadequate amount of fuel pressure or volume plus spark, and it's quite a diagnostically relevant distinction to make. The overheating story told here doesn't lead me to think "failing fuel pump." If someone can connect those dots for me, please do so.
