1987 Mercury Lynx mileage: 139,000. I am trying to find the location of the fuel pump relay on an '87 Mercury Lynx Hatchback (1.9 l with central fuel injection [CFI] and passive restrain system). I have called four local Mercury dealerships service departments and have received comments that the relay is: back near the inertial cut-out switch; behind the glove box; in the engine compartment on the left wheel well under the master brake cylinder; in the engine compartment near the ignition module. I have not been able to find it in any of these locations. Could you guide me to this relay? Please! Thank you.

It is located under the left side of the dash above the brake pedal. It is the green colored relay.
