The relay is located on the fire wall. It's only purpose is to prime the fuel system for 3-9 seconds. The circuit goes through the oil pressure sw and then to the pump. Look for a green connector that is not plugged in. apply 12v power and if the fuel pump runs it isolates the pump. Make sure you have checked all the fuses.
