I am working on an 88 formula with a no start condition. We have determined its the fuel circuit. If the relay is unplugged and the fuel switch jumped the pump in the tank did worked. But i dont know if it was before I messed with a relay mounted to the body just infront of the tank, shop area was loud. Does anyone know what the relay is, it has four or five wires to it?
It needs a new under hood fuel relay and possible fuel/oil pressure switch, but I still need to determan if I can discard the relay in the back or not.

The relay in the back must have been added after market. The fuel pump relay is on the fire wall on the driver's side in a cluster of other relays for the MAF system.
