You need to find out if it's on the control side of the fuel pump or the power side. Terminals 87 to 30 "jump" the relay and supply power to the pump. Look at the relay terminal end for the numbers. I would do that to see if the pump operates. If it does, it's the control side. If it doesn't it may be the power side. Use the test light upstream of the relay to check for voltage there too then work your way down. Always check the power side of the fuel pump circuit with a test light not a volt meter. One strand of wire will show voltage presence, but not carry a load. Hope this helps. Gerard
