Thanks for the replies. Yes, new fuel pump module/assembly with the whole deal - which I assume has the new sock, and a new in-line filter which I have verified is on there.
When I had the whole air intake mess apart yesterday - which I really did just to gauge how long it was going to take for half-way point of getting the fuel rail, injectors and pressure regulator and other assorted sensors down in there - I didn’t see or smell any gas. What I was hoping to do is to take the suffering car out for a 20 mile wasting-gasoline drive around in circles every day until I got to just under 1/4 tank - then add a bottle of cleaner and fill up with (hopefully good) gas to see if that helped. I don’t know what a dying fuel pressure regulator would cause, but I would think what I am seeing would be close. It would be a big coincidence for anything (compression, spark, air) to also fail at exactly the same time the fuel pump died. That’s why the fuel system still has my attention for than anything else.
