I recently made a purchase of an ’87 Honda 350 fourtrx, it turns over has good compression, and has spark intake is not plugged, the issue is no fuel, because the pump is not running. In fact the control head does not light up at all either I’ve been testing for several hours tracing wires, the only wore that is hot off the key switch other then power going to it is a pink wire which goes to an odd thing on the handle bars I’m unsure what it is. But other then that nothing powers up, all fuses have power going through them I’m curious about the fuel relay, but I am unsure how to test the relay because it is not a standard relay at least from what I am used too. Maybe also the kill switch? Not sure how to test this either as I have no wiring diagrams. Any advice, testing know how of any kind related to this Honda system would be greatly appreciated.

Thank You,
Cody
