Arlene, this problem sounds like the fuel pump resistor is either bad or has been unplugged. My answer to your 1st question is directly related to the condition you are seeing now. If you do replace the resistor have your mechanic relocate it from the fenderwell area to either the inner fender or the firewall. There is plenty of wire to relocate, and the resistor will get plenty of cooling and will be out of the area of the fenderwell where it may take an unwanted bath or battering by adverse road conditions. I hope this helps.
