The pump is actuated by the double relays. There are several conditions
that can cause it to fail. The rust and bad connections may be the
biggest one.

I just went all over my fuel pump circuit,  to learn why it was always
on with the key. Not much to it, so if you like,  I will write something
up for you in the morning. Do you have a voltmeter, or a 12V test light?

Do you have a Bentley, or other manual that describes the double relay
connections. I can scan it, and pmail it to you if you like.

Be back in the AM. :-)
