16v fuel pumping woes

[blake at clockworm.com (Blake Irvin)]

ok - i think i described this wrong.

looking at the bentley, i'd say for sure the part that was making
the sound (sort of a dry hum, not a buzz) was the accumulator.  so i
think it was the sound of fuel rushing into the accumulator cylinder
(?).

i don't get this anymore.  i CAN feel the tank pump vibrate when i
turn the key to ON, but CAN'T feel the main pump (under the
passenger's side?) vibrate.

so i'm guessing either bad connection to the main pump, or bad main
pump.  no fuses are bad, and i don't think my relay is or the tank
pump would not vibrate.
