                                   thank u

Answer
I am NOT positive as to the relays location on a Buick.

However, On an Oldsmobile it is located on the firewall above and to the right of the valve cover.

On a Chevy it is loacted on a bracket near the right side  headlights.

Thee are 5 wires going to the realy and the wire colors are:

ORANGE with a BLACK stripe.
ORANGE.
DARK GREEN with a WHITE stripe.
GRAY.
BLACK with a WHITE stripe.

Also you should see a female connector attached to NOTHING that has wire colrs of ORANGE with a BLACK stripe wire of which is the FUEL PUMP TEST CONNECTOR.

If you have a test light BACK PROBE the gray wire with the test light and as soon as you turn ON the ignition switch, The test light should illuminate for 2 seconds ONLY and then go out. At this same 2 seconds you should be able to hear the fuel pump in the gas tank running for this 2 second period.

DOES IT and do you have illumination at the gray wire ?.

let me know.
