Your 1991 Mitsubishi Mirage GS stalls when starting up why?

I have a 94 mirage, same problem. After changing several parts... seems the problem is the fuel pump relay. This relay is also called the ignition relay. Available only at NAPA. $76. Its metal, 8 pin, 2" x 2" maybe behind the radio. The check is: hear if the fuel pump will turn on for the second before starting.
