unknown at this time.
using a good sized jumper wire with vehicle ignition system off apply battery direct 12v to the A3 terminal on the under hood block with your fuel pump relay removed(in picture below) and listen fo ryour pump running. It is a direct line to pump. You will now right away if it is the pump or computer(has total control in the 99's).

CAUTION the image is from the bottom looking up so don't mess it up.
