My apologies to the rest of the list, a direct reply bounced with "illegal
address", but then again this probably applies to all FI bus owners.

======================
Lisa - if your fuel pump relay is flakey, then, in my experience in a very
similar BOSCH setup in BMWs, your vehicle's "main" relay probably is not too
far behind with similar behavior (in fact, it may be the culprit and not your
fuel relay - also another possibility is a worn contact on your ignition
switch between the start and run positions). Because (at least in my BMW) the
main relay is unique and cannot be "swapped" with another same p/n relay used
elsewhere in the car, if the main relay goes, you are stuck /DIW [Dead In the
Water]. (In my car, the fuel pump relay is NOT unique and can be swapped for
the same p/n in some other circuit.)
These relays are relatively inexpensive and can be changed easily (if you can
find where they are). I strongly recommend that you change both at this time.
I also carry spare relays for those two circuits, "just in case". Don't ask
how I know and how long/many times . . . .:-( .
