As you well know from being on the forum for many years, the fuel pump on those old 460 F53 are prone to failure. I'm sure you also know the fuel pressure test needs to be done while driving at WOT. Should maintain about 32#. NO catalytic on 94-97 F53.

And they tend to work intermittently a lot too, until final failure.
Right when you think you've found the problem they act up again.
We fought the battle until we finally changed both fuel pumps, added a partial Banks kit, and took care of the converter.
