I'm looking for help from the collective wisdom that so selfishly flows here. I'll start by emphatically stating I know nothing about automotive repair. I have a service department I trust and have my vehicles serviced regularly. My brother has a Taurus, about 6-7 yr. old with 60,000 or so miles. Stops running, restarts when it cools down. Is told he needs a fuel pump, and was quoted $650 total. Does this sound reasonable?
