    '99 Deville stalled and wont start

    To start a new thread regarding my Deville.

    Twice over the last month, traveling @ highway speeds, slowed to an offramp
    and she stalled - but started right up and ran fine.

    Last nite, same deal, but would not start up and has not started today either.

    Pulled codes per other threads, seeing: (marked current)

    and others marked 'history'

    Is the P0231 signalling the fuel pump has quit ?
    Is the '99 one of the cars where an access port may be either in the back seat or trunk ?

    Thanks, as always, for your help and suggestions.
